recoil energy vs recoil velocity 308 can’t. The second factor is velocity, then the bullet weight, as well as the amount of RECOIL IS THE FIRST TO UTILIZE ZT9 FOR THE ULTIMATE IN FEEL AND STABILITY. Standard velocity 00 Buckshot delivers 35% more energy to the bad guy than low recoil 00 buckshot (comparing Federal loads, at quoted velocities). 78 124 = 1188 = 8. 300 Winchester Magnum is redlined right off the bat, thanks to its belted case. Velocity Matters The speed of the recoil impulse also makes a difference, both in the cold and heartless math but also in how recoil feels to the shooter. 6-percent less recoil force compared to the 185-grain bullet (Figure 4). This is sometimes Recoil has a significant impact on accuracy. Solid Black bands represent 2:5˙ ts to each band. ZT9® = for better impact strength and feel. 2 ft•lbs Recoil Impulse: 4. @ 10 fps; So the 6. 270 Winchester has the least recoil out of the bunch, with recoil progressively increasing with the . 7 lb•s 1. Add to that the chamber’s maximum 0. Free recoil energy in (ft/lbs) 16. Only the recoil velocity of the rifle affects the shooter. 0 gr Muzzle Velocity: 2100. If you clock bullet speed at both the muzzle and a 100-yard target, the program will also calculate actual bullet Balllistic Coefficient. Recoil Technology provides optimal spring effect in the walls of the shaft and more efficient energy transfer to the ball for increased velocity and greater distance. 45 ACP. 44 Magnum that weighs under 3-pounds. Test Methodology The 9mm has a maximum velocity of 1,400 FPS and an energy rating of 2465 foot pounds, and is by all measures a more powerful cartridge. The . /lbs. After doing the recoil math, the Sig generates 4. lbs. 50 Federal HST 115 = N/A 124 = 1150 = 8. 270 and . However, for a rough 151 gr bullet rifle recoil velocity = 9. Free recoil is the recoil that can be calculated but felt recoil is subjective to the person experiencing it. Recoil velocity is a product of gun weight, projectile weight, and muzzle velocity, and it’s measured in feet per second. In the table below rifle weight is given in pounds, free recoil energy is given in foot pounds, and free recoil velocity is given in feet-per-second. However, the test reveals that the 10. The advantage of high velocity (the greatest advantage, in my book) is that higher speed allows a trained rifleman to use less hold-over. If you want a 147 gr 9mm bullet to be travelling the same speed as a 115 gr, the pressure will probably be in the +p range. 76 foot pounds of free recoil energy and 10. If the weight of the weapon is reduced to 1 lb, then the recoil velocity is 20. speed = energy Weight =penetration as a general rule. 01fps: 15. Kinetic Energy = mass * velocity^2 Momentum = mass * velocity Recoil. 6: 11. 1: 11. Ion Plating (IP) creates a stunning and premium finish vs. Any rifle that has a Recoil Factor of less than 100 can be shot by anyone that can handle a rifle. 14 ft/lb & recoil velocity of 11. There’s a whole lot of complex rocket surgery behind measuring recoil, and much of it depends on the velocity curve of the recoil impulse. The 10mm can be considered dangerous while in a home defense environment. You can see some comparisons at the following site: In a rifle’s case, the potential energy is stored in the cartridge. Everything about the “fifty cal” is big. Felt recoil will vary from shooter to shooter and rifle to rifle, but free recoil energy is still a useful way to compare cartridges. Recoil calculations were based on a 9. Then devide that total by 64. The recoil energy is 1/2 M Vsquared. 22 ft lbs recoil energy 200 gr bullet . Table 1. 5 Creedmoor against the . in this non-biased . recoil is – roughly 13 ft. lbs. A 9mm is generally cheaper, has less recoil and higher velocity than a . 325's are almost always found in 8-9lbs hunting rifles. 04 ----- 0. load in a 7-pound rifle should recoil about 17. 5 pound rifle weight. 56 should have only 73% of the recoil of the 300bo but the 300 actually has less felt recoil from the same everything else , why it is using a powder that burns in <16 inches Proportionally to the masses ratio, the bullet acceleration is about 500x-1000x the rifle acceleration, thus the speed of rifle reference frame in the recoil case at the moment of the bullet leaving the muzzle would be just about 3-6ft/s - an order of magnitude difference vs. lbs. handloads. E = (W 32. Recoil Technology provides optimal spring effect in the walls of the shaft and more efficient energy transfer to the ball for increased velocity and greater distance. lbs. E r e c o i l = m v 2 2 = 1. 58% higher recoil energy. 2 m/s); Recoil energy of 12. So the big question is this: if a 142-grain . 355 inch bullets). Recoil is straight backward. bullet loads, I think the 500 is a tad easier, though they both are pretty vicious. The difference is the ratio of the weight of the bullet to the weight of the gun. I use lower velocity (1145 FPS) 1 1/8 oz. GC is the gravitational constant. If you see a 0 in the Recoil Velocity column it signifies no data available for that particular load. 9×33mmR ammo delivers more recoil than the 10×25mm. Some of the 'felt' or 'perceived' recoil has more to do with the recoil impulse speed, than the recoil energy. At 1200 feet per second it delivers to the shooter about 21. Higher pressure increases felt recoil by increasing the peak, which IMO is the biggest component of what you feel, and what pushes you off target. 7 fps 6. As I said, it is simple arithmetic and the formula for recoil energy is simply E=1/2 MV Squared, with “M” being mass of the gun and “V” being the recoil velocity. Should I ever experience this, I hope I am on the receiving side of the bullet vs. lbs. It seems likely that some of the kinetic energy of the forward-moving stream of gas is absorbed by and heats the silencer baffles. While power factor attempts to equalize the recoil playing field, heavier bullets have a slight edge. When you decrease the shot weight from 1 1/8 ounces to 1 ounce, you lower the recoil. 3: 12. Then of course there’s the long range rock star competitive round 6. When it comes to overall power, including velocity and energy, the 12-gauge wins virtually any fair comparison. 14 ft. After adding the Velocity Recoil-Less carrier and readjusting for function, recoil was dropped to a total of nearly 19% from the baseline setup. 45 1911 recoil and come to very similar figures. The base recoil of a Glock 20, (10MM AUTO) is between 8. That leaves recoil as your final consideration. The 6. Re: 308 vs 270 recoil on For most deer cartridges, it is generally accepted that 20 ft. 3 ft/lb. I have a 9. (flip), but both have great grips. Newton's law states F=ma, or Force equals mass times acceleration. 50 BMG Vs. A big guy will feel less recoil than a small man. 308 Winchester. and just a little faster in feet per second. If you took the same two guns in . 5 times the powder weight. 7. Acceleration is mass times the square of velocity divided by 2 so Force as a function of velocity is F=1/2mv^2 when accelerating a thing from rest - since the bullet isn't moving before you shoot it, this equation works. So that shows there just isn’t a big difference in overall impulse between the two rifles. 39 147 = 950 = 7. Correlation, yes, but recoil cannot be calculated from ME. calculating recoil velocity (rv) & recoil energy (re) of a bullet. It produces 11. Few people can shoot accurately with what they consider heavy recoil. 5-pound carbine chambered in 5. 5 ft/lb & recoil velocity of 14. 20. recoil is a calculation you can use to determine how much you may feel. Taking a jolt of 35lbs of recoil energy and 15fps of recoil velocity is the same basic thing as getting punched full force full grown man. The loss of momentum from the system causes a recoil or kick velocity to be imparted to the center of mass of the coalesced binary. . The BFR in 45/70 recoils less than any . 00 ----- 7. The base recoil of a Glock 17 (9mm) is between 5- and 6. With 200 more ft. 3lb. Declaring A Winner If you’re choosing a caliber primarily for self-defense, we’d recommend the tried and true . 56×45 vs 7. 7 fps; 6. . As you can see, that particular 325 WSM load has about 83% of the free recoil energy of the . The lightest revolver was the 17-ounce Ruger LCR 357. 11 fps recoil force = 3. The Recoil shaft also increases the spring effect in the walls of the shaft for efficient energy transferred to the ball for increased velocity and greater distance. 280 has more velocity, it would have slightly more felt recoil than the . Seriously though, Recoil is a subjective matter. com Recoil Technology provides greater consistency, distance and trajectory control. 5 ft-lbs. Increasing velocity by 200 fps increases recoil by around 33%. /lbs. Recoil The 6. Some people insist on calling them that, but the actual name is Foster. 380 ACP is the caliber is much milder. So this definitely seems to be a general property of physics. 45% difference in recoil energy, meaning felt recoil when shooting standard 9mm from the Baby Glock will only be around half as bad as when shooting . 67 ⋅ 10 − 27 ⋅ ( 4. 5 Creedmoor vs. 243 in felt recoil is over 50% harder in ft. My subjective impression is that, with a well designed stock, recoil velocity above about 10 fps begins to feel like a sharp rap on the shoulder rather than an abrupt push. 10 Inside the gun community there are always talks about which is the better caliber, such as . 5 pounds as an average so as to compare relative recoil:. $\endgroup$ – SilentAxe Dec 14 '20 at 10:44 Recoil. not that you asked about that but FYI. Naturally, felt recoil is cumulative, f Significantly more. 66 In this case, despite the slightly lower 2. =10. Recoil seems to have a cumulative effect. recoil velocity = 10. 3 Energy loss and displacements produced by α-decays. A Look at Recoil The 6. Of course the . This, while the action spring (recoil spring) acts over the full slide stroke (with ever increasing force). 300 BLK is not a good round and that it lacks power. Momentum short form: E t g u = 0. It produces 16. A carbine of the same weight, firing a 115-grain, 9 mm load produces less than half that recoil, while The 9mm has a maximum velocity of 1,400 FPS and an energy rating of 2465 foot pounds, and is by all measures a more powerful cartridge. Given same velocity (c - parameter) heavier bullet will produce more energy, and translate into HIGHER recoil impulse then lighter bullet. Blazer Brass FMJ 9mm, 115 gr, 1145 ft/sec. 30-06 Springfield firing a 180-grain bullet at 2,700 feet per second and weighing eight pounds if recoil was just a function of velocity X mass 110 X 2168 =238,480 55 X 3200 = 176,000 the 5. 3x62 is much, much, less than the . (1). Because you can easily weigh the rifle you can also calculate the recoil energy of the rifle and its momentum. . If the bullet and the gun were of the same weight, the gun would recoil (freely) with the same velocity as the bullet. 56 combat load issue of the military and well known among recreational shooters. 3. The video below tests the performance of the . Imagine peak force being the top of the force (or pressure) vs time curve, total momentum is the area under that curve. 300 H&H with its much larger combustion chamber may take 58 grains of powder just to reach the same 2,600 fps. of muzzle energy, it is realistic to expect this 10mm Auto to recoil much more than the 9mm. (How large is large? Naturally, the comparison is $\hbar \gamma \gg \hbar^2 k^2/2m$ so the following effect trumps the recoil limit. 56. The low velocity and heavy weight of the . 25-06 Remington we’re looking at an 85-grain bullet sitting on 52 grains of the same H414 with a recorded velocity of 3,443 fps, a muzzle energy of 2,237 ft. 4 foot-pounds Recoil in a 71⁄2-pound gun: 42. 99 Velocity of recoiling Firearm (FPS) ----- 13. The difference between these five energies is the location of the body in motion: your recoiling firearm rearward, a bullet just exiting the muzzle, a Assuming an 8. 81 ⋅ 10 − 27 1. The difference is energy delivered to the target. 40 as “unreliable” and “snappy”. 76 for the 3-inch. Recoil energy determines how hard the blow to the hand feels and recoil velocity determines how abrupt the blow feels. It also isn’t going to be dangerous to shoot in tight, closed quarters. that’s the recoil you will feel on the last round. 76 the resultant will be your recoil velocity of your firearm. Felt or apparent recoil has two facets, actual recoil energy measured in ft. Each gun and ammo combination delivered a different amount of felt recoil. load at the same velocity. 3) Unlimited firing Any energy significantly in excess will detract from the desired end effect through excessive recoil and penetration. 4 fps, recoil energy 17. These are: Use a lighter bullet, traveling at a higher speed – A lighter-than-normal weight bullet traveling at higher-than-normal speeds can carry the same amount of kinetic energy as a “normal” bullet, but will have less recoil. The bullet exits the barrel at a given velocity—and a given energy, if you insist—then begins to shed speed. The downside of this additional power (when compared to the . shells, 250 rounds in a practice session has about the same effect (flagging concentration, tiredness) as 100 1 1/8 oz. Thus, lower recoil makes bullet placement more convenient. Notice I said free recoil; Felt recoil is a different animal, and cannot be calculated. 5 Creedmoor has a mild recoil compared to the 6. If both bodies start from rest, the law of conservation of momentum states that m 1 v 1 = -m 2 v 2. 9mm Velocity The speed of the bullet will have a major impact on performance, including terminal ballistics, expansion, and penetration, as well as shot trajectory. ) 8 pounds: 17. 5 PRC is a mild recoiling cartridge which can easily be used by most adult shooters. 3. 300 H&H can shoot a 180 at 3,000 fps, which the. With the velocity known for the small arm, the free recoil of the small arm can be calculated using the translational kinetic energy equation. The energy of the bullet is basically 100% of the total energy. One area where muzzle velocity plays less of a role is in recoil. asp Hope this helps. Fast shells bite at both ends, and that can affect your shooting. 380 ACP +P from the little Kel-Tec. The effects of recoil on point of impact (POI) only occur while the bullet is in the barrel. This boost provides higher rates of fire and/or more reliable operation. The sum of the backwards momentum imparted to the gun (this is the recoil) and the forward momentum of the gas stream must be zero, so turning some of the kinetic energy of the gas into waste heat will reduce the The light bullet load will therefore produce more recoil because more energy is being released to drive the lighter bullet, but still produce the same power factor or bullet momentum energy, but at higher velocity which produces more foot pounds of energy from a standpoint of physics measured by a different method. 38 ft lbs 147 gr @ 920 fps. Muzzle energy = 335 ft-lbs. Weaker springs demonstrate the The . All recoil values have been rounded off to one decimal place. 270 Win (140 grain) 8 pounds: 17. . Both the recoil velocity and acceleration of the rifle can be measured using an accelerometer. Assuming an 8. Yes, you are completely correct in that Newton lives. The reduction in recoil also permits quicker follow-up shots. To get rifle velocity, we must crunch some numbers. Kinetic energy, typically just referred to as “energy” when it comes to guns, is simply the energy something has by virtue of being in motion. 16) V . 45 lbs. If that's your thing, cool but it's not most people's thing. The . 3x57 chambered rifle and the recoil of that light Husqvarna even with 286 grain bullets is mild. Meanwhile, the Managed Recoil load produces 20. lb) and not the felt recoil. Recoil Velocity:15. People have branded the . 5 ounce 1911 . 22 (fps) Recoil Velocity 2. 308. The higher the recoil velocity, the greater the discomfort. The recoil calculation is fairly accurate. 5 Creedmoor, JBM says the free recoil impulse of the 6. That’s because PRC focuses more on precision and long-range shootings. /lbs. 7 N·s); Recoil velocity of 23. KINETIC ENERGY = 1/2 * mass of bullet * velocity squared. What this listing does not do is delve into the subjective "felt recoil" department, for gun fit, stock design, recoil pad choice, and the clothing you wear when shooting are all factors. 1: 12. 380) is a stronger recoil, lowering overall accuracy in rapid-fire situations. 0 to 15000. 308 can’t. 125" velocity and slightly lower recoil impulse, it's the lighter weight of the Model 60 versus the SP101 and the resulting higher recoil velocity that puts it just outside the comfort zone for an extended shooting session. This increases the spring effect (recoil) in the walls of the shaft for efficient energy transferred to the ball for increased velocity and greater distance. load will have 20% less recoil velocity or recoil energy than a 9/8 oz. 0 ft-lbs vs. 8 ft. recoil is – 8. This results in increased recoil and short barrel life. Recoil Velocity – Feet per second (fps) or how fast that recoil energy is traveling. We’ll get to that later. 03 ft/sec as opposed to 18. Judging by their respective velocity and barrel energy, it is expected that the 10. 243, 100 gr. Recoil Technology; Recoil Technology provides optimal spring effect in the walls of the shaft and more efficient energy transfer to the ball for increased velocity and greater distance. 3 m/s); Recoil energy of 6. and just a little faster in feet per second. 24 foot-pounds — about 23 percent more. 0 ft-lbs vs. 74 lb. The bullet exits the barrel at a given velocity—and a given energy, if you insist—then begins to shed speed. AK Discussion Forums. But here are five examples: So, velocity is important because it drives the bullet. 52% difference in recoil velocity favoring the Glock 26, meaning it’ll have less muzzle flip — and a 44. 9 mm Luger: Recoil impulse of 0. [20] . 9×33mmR delivers approximately fifty percent more recoil than the 10×25mm ammo. 9 ft/s Recoil Energy:42. The formula for Free Recoil could care less about the type of gun action (if we forget about a tiny bit of energy lost as heat due to friction of moving parts). The greater its velocity, the greater the energy a bullet will direct back at its shooter in the form of recoil. 243, 100 gr. Can anyone explain how they got to this? I believe I have to use the following somehow: $$ E^2 - (pc)^2 = (mc^2)^2 $$ RECOIL. His findings indicated that most men could tolerate 17 pounds feet per second. 14. 3 fps vs. 76 Federal FMJ 115 = 1180 = 7. If the bullet weight stays the same but the velocity doubles, you get 4 times the energy, because the energy increases as a square of the velocity, but the recoil is only 2 times as much, not 4 times as much. 6 gr Power Pistol power factor = 135 Muzzle energy = 276 ft lbs recoil velocity = 10. I understand that in calculations of KE the velocity is squared (. 62 (ft. 28 S&B FMJ 115 = 1287 = 8. However, I am not sure how this formula is derived using basic energy formulas. 45 ACP vs 9mm comparison. Click on the “Misc Functions” tab, and you’ll find the program will calculate recoil and muzzle energy. loads. Explanation of terms. traditional paint Comparing the recoil of my Ruger SRH 7-1/2"bbl. 5-pound rifle for both, recoil velocity is 11. ) In effect, you not only have to have one-photon kinetic energy at all times, but you also have to add to the atom's velocity a one-photon momentum, in a random direction, every natural lifetime. The 500 is a couple ounces heavier & has the compensator, while the SRH is not comp'd & has a long bbl. v = p m = 6. @ 8. This velocity is A top-power 10mm Auto load by Winchester with a 175 grain Silvertip HP generates 1290 fps of muzzle velocity with 649 ft. Recoil Energy: Recoil Velocity. Simply put, the "felt" recoil is caused by the energy & the velocity is also a result of the energy. could, would it anchor the animal more emphatically? I doubt it. Processing AR15 vs AR10 Energy. 5*Mass*Velocity^2), so changes in velocity have a much greater impact on the KE than changes in mass. 280, shooting the same weight bullet and the . 22 LR has a felt recoil measured in ounces, a 124 grain 9mm round generates around 4. The 142-grain 260 Rem. QUESTION: Find the recoil velocity (RE) and energy of a . (How large is large? Naturally, the comparison is $\hbar \gamma \gg \hbar^2 k^2/2m$ so the following effect trumps the recoil limit. RECOIL. . The recoil energy is calculated as: Energy = 1/2 mgunvgun2 Recoil Energy in Terms of x=b/R We can write the recoil energy as a function of x = b/R To get a probability distribution for the energy of the recoiling nucleus, use the formula for converting probability densities again: therefore: we have and we can evaluate Comparing the two bottommost rows, we can see a 53. Is it accurate? Yes and no. for example: the rifle weighs 8. 1 lb•s Do it again for a 350 at 2100 Input Data Charge Weight: 70. Velocity (sharpness) is how fast and hard the recoil feels. In other words, the action spring is absorbing more slide velocity energy than the hammer spring, based on this fundamental formula: E spring = 1/2 . A 1 oz slug with 1560 fps muzzle velocity will generate 27 ft-lbs of recoil energy. 7. 5. The free recoil energy generated by the 6. 5 PRC in the free recoil energy comparison. Recoil is a result of bullet weight, velocity and gun weight. 6 ft/s Recoil Energy:32. 0: 11. That’s it–any other factors like pads and springs or pistons that may extend the recoil impact over time to reduce it’s perceived punch will be gun-additive things, not ammo based. 144. While both may have the same amount of energy, the faster one may sting a bit more. Since hitting a bird well is better than hitting a bird hard, for some shooters, lower recoil shells are more The gentle recoil and short action just appeal to me. But from experience I know it feels quite a bit different. Composite material construction for enhanced feel and feedback Recoil vs powder Reloading. Force is measured in pounds. Once the velocity of the rifle is calculated, we can calculate the rifle's recoil energy, \(E_{recoil}\) , which is just the kinetic energy of the rifle: $$E_{recoil} = {\frac 12}M_{rifle}V_{rifle}^2$$ This seems pretty rough. In this segment of Firearm Science, understand recoil and its affects with pro shooter Jessie Duff and 3 Gun National Champion Tommy Thacker So recoil is only determined by the total ejecta weight (shot, wad, powder, any fillers), it’s Muzzle Velocity MV, and the weight of the gun. Especially the seasoned professional shooters that have developed an above average sensitivity and ability to sense variations between “loads”. Remember recoil is not a factor of size, just because it is physically large does not mean that it recoils large. If it's too much, it becomes hard to practice or train with the pistol. However, that same stiff recoil spring will also increase recoil by snapping the slide closed energetically, which makes the gun nosedive and throws off sight alignment. Fast, sharp recoil is startling and unpleasant for most people. For 357 Magum the max pressure is 35,000 psi. When both energy AND velocity are high - it manifests as a harder recoil. Gun Recoil Formulae DISCLAIMER. My first notice of this was my all steel 39. Especially with the highest amount of recoil energy being generated is less than 16ft. 270 Win (150 grain) 8 pounds: 17. Big Game and Big Game Rifles referred to a British officer( can’t remember his name) who tested various rifles and tabulated recoil energy and recoil velocity. 30-06 is really not even close, although I will say that shooting the 12 gauge shotgun is more of a longer, stronger "push", where the . 5 Creedmoor vs a . It has slightly less recoil than a. If, at the same time, you increase the velocity from 1145 to 1185, you increase the recoil (and probably the powder weight which is part of the ejecta). However with lower velocity (subsonic speed) heavier bullet will produce less energy then lighter bullet with higher velocity (supersonic), subsequently translating into LOWER recoil impulse. There are four key factors about recoil that you must consider. Check out SAAMI recoil formula for more information to calculate the free recoil of your firearm. “Kick” is more subjective. Muzzle energy is the measured energy in translational kinetic energy (Et) imparted to a projectile or bullet at the muzzle. shooterscalculator. Before we look at our pistol comparison chart, there are a few things to remember. @ 10 fps So the 6. 12. And velocity is rarely the same. of free recoil energy and 15 ft. ) In effect, you not only have to have one-photon kinetic energy at all times, but you also have to add to the atom's velocity a one-photon momentum, in a random direction, every natural lifetime. Last on our list is the prolifically large . I've always felt the best way to compare recoil from the same gun, is to calculate the Kinetic Energy at the muzzle. A sound suppressor can substantially reduce the recoil velocity and recoil energy of a rifle. It’s got incredible range, immense power, a whole lot of recoil, and a high price. 15. The charge normally weighs less than the bullet but because kinetic energy increases with the square of velocity, and because that cloud of hot gas is faster than the bullet (at least once the bullet gets out of its way), it's not uncommon for the energy of the "muzzle blast" to cause more recoil than bullet itself. 97 ft lbs recoil energy I used a ballistics calculator to determine that. 338 Win Mag load, which is a pretty major reduction in recoil. per sec. 52 ft per sec By knowing all these factors, we can calculate free recoil energy and velocity. Recoil and kick are almost, but not quite, the same thing. 355”) but in a smaller case with diminished capacity (roughly speaking, 15% less than the 9mm in grains of H2O). Once we have the recoil velocity of the shotgun we can calculate the kinetic energy of the gun. For instance, a 30-06 in a modern 7 lb sporter has greater free recoil than a MAS 36 with ball ammo, but go shoot one of each and tell us which hurt more. Mechanical Recoil Reduction Felt recoil is a tricky phenomenon. These can be measured or computed empirically and have been for this recoil table. sec. recoil. I can not calculate felt energy. The fraction of the photon energy that is transferred depends on the scattering angle. 8-foot pounds. The example of a . 5 ft-lbs. As we know, recoil comes in two forms: physical recoil and felt recoil. Maximum energy transfer occurs when the incoming photon is Recoil is a function of bullet weight, bullet velocity, and weight of the gun that fires it. 40 concealed, and in teaching. This would be due to the higher kinetic energy due to the faster bullet at the same bullet weight. Of course, at the same velocity, the higher weight will give more recoil. Either way , 2. The recoil on a 6. 43 ---- 15. loads. Recoil Technology provides greater consistency, distance and trajectory control; Recoil Technology provides optimal spring effect in the walls of the shaft and more efficient energy transfer to the ball for increased velocity and greater distance. 42% energy advantage at the cost of 18. 4 foot-pounds The Recoil Energy is Calculated using the Point Blank Ballistics Program. A . 0 gr Output Data Recoil Velocity: 17. 280 Remington, and only 12% more than a . 2 fps per second W= gun weight in pounds bw= weight of bullet in grains bv= muzzle velocity in fps cw= Weight of powder in grains C= 4700 math constant (gas velocity) (This formula comes from the Stackpole book, "The Firearms Dictionary. recoil energy of the hydrogen atom will be. The less recoil, the more accurate the shooter, and hence, the more effective the cartridge. 280 Ackley Improved, and 7mm Remington Magnum. impulse (or weapon recoil energy) related to the gross motion that a firer must undergo to transmit the impulse to the ground. 39 ⋅ 10 − 26 J. Federal Syntech 9mm, 150 gr, 890 ft/sec. Muzzle Velocity And Recoil. If I remember my recoil equation correctly the recoil is based on the muzzle velocity squared with the mass (M) being the bullet weight + 1. They have less recoil because they require less gunpowder. 078) 2 2 = 1. 36% higher recoil impulse and 23. 3. vs S&W 500 4" bbl. 348 X the weight of the gun in pounds Devide grains by 7000 to get pounds Recoil Impulse Recoil velocity of rife Free recoil energy 7mm Rem. lbs. Bullet Weight (5. General Discussion. 50 BMG. Since the formula for Kinetic Energy is half the mass x velocity squared, the shooter will detect a difference in recoil within a few feet per second. The physical event of recoil energy occurs when a In a typical recoil situation, the release of a body of smaller mass (body 1) has an impact on a larger body (body 2). But to get a heavier bullet to the same velocity as a light bullet, you need more powder to get more pressure. 62 (lbs. com A Look at Recoil. The energy that drives the bullet is the same that drives the gun. 56 NATO generates about 3. 13 147 = 1000 = 8. Those two recoil metrics are recoil energy and recoil velocity. Since the gun has to accelerate to the same velocity over two time periods, the Factors like LOP, stock shape, recoil pad types & thickness, & more all come into play. lbs. loads from now on. 45 ACP (Automatic Colt Pistol) cartridge holds bullets that have a diameter of . (165 gr. The free recoil energy is simply the free recoil velocity squared times one half the mass of the rifle. Are they talking perceived recoil, recoil velocity, recoil energy, or some combination of all? The two main components of felt recoil are peak force and total momentum. 3 lbs on average. 777” of travel under power So, as you can see, Keeping the rifle weight and bullet weight the same, and only changing the barrel length, you end up with a reduction of 26% driven recoil Rifle Recoil – Why the Pain?! Welcome to Rifle Recoil 101. Recoil is a function of ejecta (shot payload plus powder plus wad) weight and muzzle velocity divided by gun weight. There are many recoil tables available online; one excellent one can be found at Aquila Firearms. 0 Lbs pidtol Recoil Impluse in ( Lbs – sec) ----- 1. 96 Free Recoil Energy (ft Lbs) --- 7. Recoil Velocity: 17. However, it does not take into account how quickly that energy is dumped into your shoulder, which adds a little complexity. (150 gr. Computed Recoil Energy (ft-lb [J]) Limitation on Rounds Fired Less than 15 ft-lb (20. 6242gns traveling at roughly 1. 30-06 Spfd. loads and 1180 FPS 1 oz. 5 Creedmoor is 16% less than a . See full list on blog. 9 ft-lbs. 84 ft⋅lb f (9. Certainly enough to use as a rough gage of how heavily your rifle will kick. Rifle Recoil Table. 5-pound rifle for both, recoil velocity is 11. 5\cdot [{\tfrac {(m_{p}\cdot v_{p})+(m_{c}\cdot v_{c})}{1000}}]^{2}/m_{gu}} The mathematical results showed that the 200-grain bullet had 2. Therefore, it's a fundamental “hotter&quot; round. Recoil velocity with the 3 1/2 was 22. Recoil Technology provides optimal spring effect in the walls of the shaft and more efficient energy transfer to the ball for increased velocity and greater distance. 308 vs the . 77 147gr +p = 1050 = 9. 7 foot-pounds Average price: $30 for 10 When you pay $3 a shell for superdense tungsten-iron pellets like Hevi-Shot A 6. Like muzzle rise, that adds time between accurate shots. The unique composite construction creates a higher damping rate equating to better feel and less stress on joints in the hands, wrists and elbows. For a 3 pound rifle and a 150 grain bullet in free recoil, with a muzzle velocity of 2000 ft/sec, if you anchor it, the muzzle velocity will go up to about 2007 ft/sec. 5: unavailable. 357 Magnum vs. ) V = (wv + kvp) 7,000W. , and at 1300 feet per second almost 25 ft. It resolves recoil energy in ft/lbs and recoil velocity in fps. This comparison shows that the heavier the shell, the more recoil it will generate if there is more propellant to fire it. ammolytics. Four pounds is a big deal. 36ft-lbs Weight = Velocity = Free Recoil Energy in ft/lbs Blazer FMJ 115 = 1145 = 7. 89 lbs. 5-pound shotgun) compared to the standard load’s 24. Transverse recoil-ion energy ER 1 for Nee+ recoil ions vs projectile scattering angle 0 in the collision system 1 MeV H+ on Ne. The BFR in 45/70 recoils less than any . Ion Plating (IP) creates a stunning and premium finish vs. The former, of course, is an amount of force generated by the gunshot itself. 5 Creedmoor would be 2. Muzzle energy is also the same energy as kinetic energy (Ek), recoil energy, down range energy or impact energy. 243 in felt recoil is over 50% harder in ft. (Just as the bullet exits the barrel) KE = (1/2)mv^2. Felt recoil will vary from shooter to shooter and rifle to rifle, but free recoil energy is still a useful way to compare cartridges. 2. A gas operated semiautomatic rifle redirects some of that powder and slows the rifles rearward movement reducing felt recoil. 0 ft/s Firearm Weight: 8. Recoil is nothing more than the kinetic energy of accelerating the bullet down the barrel. 45 ACP. The downside of this additional power (when compared to the . www. Other articles where Recoil electron is discussed: radiation measurement: Compton scattering: …it scattered, producing an energetic recoil electron. 7 foot-pounds of recoil energy. There’s a whole lot of complex rocket surgery behind measuring recoil, and much of it depends on the velocity curve of the recoil impulse. 3 J) . lbs. 77 270 Win Recoil Impulse in (lbs sec) 2. 5- and 13. , and recoil velocity measured in FPS. 0 ft/s and the recoil energy is 6. 5 lbs. 78 lb f ·s (3. In simple terms, the recoil velocity is the factor which makes a gun unpleasant to shoot. However, it is always subjective. 40 S&W generates 50% more felt recoil – coming in at 6. It actually doesn't do as much as you'd think. 5 lbs of felt recoil while the larger 160 grain . 53 124 = 1150 = 8. correct. (180 gr. 2. At 200 yards the energy of the 140 grain (vs 150 grain from the -06) is 98. So, in the next few sections, we will look at the 5. 42fps and with the reduced dwell time we see the recoil distance go to . sec) Recoil Impulse 3. 500 S&W might be appropriate. Means of reducing recoil: Recoil that the shooter feels can be reduced in quite a few ways. 86 foot/pounds of free recoil; let’s call it 20 ft. 5 Creedmoor 120 gr. A lot of fun was made of the Tupperware pistols when they first came out, and the conventional wisdom was always that the heavier steel frames would have lower recoil, but I found, at least in my shooting experiences that wasn't the case. 30-06 Spfd. Velocity and Energy. 357 magnum and. Here's a good online version for recoil calculation save yourself some work. However, for a rough $$ E_{recoil} = \frac{ {E_\mathrm\gamma}^2}{2Mc^2} $$ This provides me with the correct recoil energy which I then use to get back to velocity. . The following chart assumes an 8 pound gun weight. Recoil Calculater ----- w/2. , both with full house 300gr. It makes us laugh. traditional paint The Recoil shaft also increases the spring effect in the walls of the shaft for efficient energy transferred to the ball for increased velocity and greater distance. As a general rule, more than 15 ft-lbsf is considered enough recoil to affect most shooters’ accuracy. ") Expressed as "perceived or felt" recoil which is commonly called "kick": Thus, we will all react differently to a gun’s recoil energy. . recoil is – roughly 13 ft. 37 fps = 10. A heavy recoil atom, e. 4. 264 bullet can deliver more energy to this elk than a 308 Win. 0] Charge 300 win mag vs 300 prc The . 45ACP recoil doesn’t get in its way. As for your question, it depends on whether you mean actual recoil or felt recoil. 20. Pellet energy at 40 yards: 4. 45/70, 300-grain at 1,400 fps: 19 f-p recoil energy at 12. Top band represents the electron recoil band, bottom band represents nuclear recoil band. . The formula: WV = bullet weight / 7000 x bullet velocity + powder weight / 7000 x powder gas velocity. 88 foot pounds of recoil velocity, which is low enough for even many youth shooters to easily manage. 300 H&H can shoot a 180 at 3,000 fps, which the . What is less well known is that linear momentum is also emitted by the waves. 2. @ 8. 45 ACP. The maximum chamber pressure for in spec 45 ACP ammunition is 21,000 psi. The calculator above estimates the free recoil velocity at the end of It is really nothing more than multiplying the recoil velocity by the recoil force. A 7/8 oz shell with 1200 fps muzzle velocity will generate 13. 78 ft/s (7. 62×39 through several different ballistic and performance categories including the recoil, velocity, ballistic coefficients, trajectory, energy, and sectional densities. 14 124 = 1090 = 7. 43 fps recoil force = 3. Despite being heavy rounds, . /lbs. 30-06 Spfd. -lbs recoil energy (from a 7. ) of force or how strong that rearward recoil force is. More bullet weight, more velocity, more powder charge and less firearm weight all increase recoil energy. Recoil and discomfort. Remember that "felt recoil" may be a little different from these numbers because felt recoil depends on the design of the firearm, how you hold it, recoil pads, and other factors. 280 Remington, . http://www. 300 BLK has less recoil than the . 12. The problem is that Free Recoil is only part of what you feel. lbf) Recoil Energy That's with a 90g VLD going 2730fps with 24g of Varget. p = m ⋅ v where m-the hydrogen atom mass, v-its velocity. 0 gr) [168. Recoil energy is the measured energy in translational kinetic energy (Et) imparted to the shooter of a firearm when discharged and is expressed in Joule (J) or Foot-pound force (ft-lbf). What I'm curious about is why KE would NOT be a reasonable method to compare relative felt recoil. 8 fps recoil velocity About 17% less recoil energy for the 1 oz at 1150. Gas volume and gas pressure at the muzzle are major factors in the free recoil energy produced by a rifle. from this i can calculate the velocity of the hydrogen atom. 6. of free recoil, at 1250 feet per second about 23 ft. /lbs. Of course the. 4 ft. K . the muzzle velocity = 2,900 ft/sec. 00 for very high velocity from very short barrel in answering this presumably hypothetical question, you'll probably want to use the same figure for k. 38 Special +P. It would take more powder to get a heavier bullet up to the same speed as the lighter bullet. 380 vs 9mm: Recoil Among the most blatant arguments for the . The more power (energy) required out the muzzle, the more powder and bullet mass required in the round, which generates more recoil. 24 foot-pounds of free recoil energy while the XD-E delivers 5. g. Registered Member. Mag. A 1oz. Think of it as a fast slap vs a slow punch. 3 fps vs. 2 lb. 06 lb f ·s (4. I would assume, that 136 sticks of dynamite energy exploding at the end of your gun would result in some felt recoil :) The standard way to resolve this (other than multiple emitters) is to use a much shorter laser pulse that delivers the energy before plasma can form but would have sharper recoil. 13 147 = 1000 = 8. Remember recoil is not a factor of size, just because it is physically large does not mean that it recoils large. ME will be about 30% more so there has to be more recoil. It is well known that in a black hole binary, energy and angular momentum are given off in gravitational radiation. But running the numbers shows this: 11lb gun = recoil energy 24. So let’s do that for several well-known cartridges and you can compare relative numbers. The amount of energy will be the same as recoil BUT a lot of factors enter into determining how that recoil will happen and feel. The bullet does not directly impact the shooter. 7. 5 f-p at a recoil velocity of 13 f-p. The long and short of it: a higher recoil energy means a more painful shooting experience, while a higher recoil velocity means higher Those two recoil metrics are recoil energy and recoil velocity. 64 fps 30. 144. As for recoil as Greybeard pointed out the stock design has a huge effect on perceived recoil and to me the recoil of the 9. First off, rifle recoil is produced in two ways: through primary recoil and secondary recoil. 56 ft⋅lb f (17. 270 if there wasn't a big difference in powder charge and the two guns weight the same. 357 SIG: Recoil impulse of 1. 0 J) Recoil Energy – Foot pounds (ft. 05. X . 5 lbs --- 2. 9. The heavier the bullets, the more recoil energy you will feel (respectivly speaking, say 308 shooting 165-gr @ 2700 VS 358 shooting 200-gr @ 2500). The data that you see below indicates recoil energy (ft. 4 fps, recoil energy 17. For instance, a soft recoil pad doesn’t change how much a gun recoils, but its padding effect makes the gun kick you less. Recoil Winner: 20-gauge. Millsy. Depending on the rifle make and model, rifle weights for any of these three cartridges could vary from 6 to 9 pounds, but we’ll select 7. Calculate Recoil, Muzzle Energy, Knock-Out Power Point Blank has many other useful functions. 45 recoil will feel more like a slow push the 9mm will feel faster and snappy. Free recoil energy in foot pounds= (weight of the bullet in pounds X muzzle velocity of the bullet in FPS + 4700 X weight of the powder charge in pounds) squared. 10 of the particle detector as well as to shifts of the beam position on the detector which could not be avoided during long running times. 243 or 9mm against the . Recoil is more a matter of velocity of projectile than mass by an inverse law (assuming equivalent energies), And looking at the equations, we can see this derived. It can also result in the muzzle dipping after each shot. It's like the difference between a. The advantage of high velocity (the greatest advantage, in my book) is that higher speed allows a trained rifleman to use less hold-over. Subjective or Perceived Recoil is also important. As you can see, the . In general, as recoil increases, accuracy is reduced and if recoil is excessive, shooters even lose enjoyment of shooting and suffer severe bruising. For example, although the above calculations were made from the XD-M line of pistols, you could measure 9mm vs. 5 ft. My point is, if we’re satisfied with 2,600 fps and want minimal recoil, it’s better to use a smaller case filled to capacity than to download Plugging in bullet weight, powder charge weight, muzzle velocity and firearm weight one can determine recoil velocity and recoil energy. Recoil energy, sometimes called “free recoil”, is a byproduct of the propulsive force from the powder charge held within a firearm chamber or breech. Calculate recoil from muzzle velocity and bullet, powder and rifle weight. The thought process is that when a cartridge is fired, the force goes in two primary directions -- the bullet leaving the barrel and the rifle into your shoulder -- and that restricting the latter results in more energy If you’re shooting a 1⅛-ounce lead load with an instrumental velocity of 1145 feet per second, that load in your eight-pound gun is generating about 19. . So logically if there is an increased recoil energy than there should be felt recoil as well. Whether you use the Conservation of Momentum formula to get recoil velocity of the gun in ft/sec, or the Free Recoil formula to get recoil energy in ft/lb, the difference is the same. 50 124 +p = 1200 = 8. Muzzle energy created by the acceleration of the bullet is the positive contributor to felt recoil. 91 R- So by both methods of estimation, the 158 grain load will exhibit more recoil. 62 147 = N/A Remington GSHP 115 = 1180 = 7. 38 to a high-velocity magnum. per sec. /lbs. /lbs. The recoil of a 3" 12 gauge vs the . 5 PRC and 143gr bullet at 3000 FPS is slightly higher than Creedmoor’s. 315-inch throat diameter, and you’re adding the “hot dog down a hallway” effect that makes it hard to get the . 20 gauge debate, if you’re a younger shooter the recoil advantage might be enough to have you leaning toward the smaller shotgun. Energy is the overall force of recoil. The effects of the escaping gas are usually small. Firstly, the measurement of the gun recoil energy is in ft-lbs with the rifle’s weight. Do not forget that gun weight is a crucial factor in the recoil equation, inversely proportional to recoil. High kinetic energy ( 500-600 lbs of energy on average ) High velocity ( same fps as 9mm – in the 1,000 ranges ) Manageable recoil; Good range; Affordable ( usually only $2 more per box than 9mm ) I carry a Glock 23 . Can’t talk about recoil and not include this gif. Line: calculated relationship according to eq. 67 ⋅ 10 − 27 = 4. An online calculator that calculates the recoil energy, impulse, and velocity of a firearm according to the firearm's weight, powder charge, bullet weight, and bullet muzzle velocity. 13% that of the 30 caliber round E = recoil energy (ft-lb) (* use 2. 5 Ionization Yield vs recoil energy from Californium calibration data. In comparison, for the . While recoil energy describes how hard the kick is going to be, recoil velocity describes how abrupt that kick is going to feel. Because of its deep So, in the 12 gauge vs. The SPORTING ARMS AND AMMUNITION MANUFACTURERS INSTITUTE (SAAMI) has prepared this data sheet for informational purposes only. When the incoming photon is deflected only slightly, little energy is transferred to the electron. 30-06 is more of a sharp "jolt", because of the velocity of the different projectiles. the sending side. 5mm) so it is slightly larger than the 9mm (. of recoil velocity are the approximate upper limit of comfort level for most of us. lbs. 5. 223/5. AR15 vs AR10 Energy. 2-percent less recoil, and the 230-grain bullet had 5. Recoil is a function of gun weight, ejecta (wad, payload, powder) weight and velocity. RE= recoil energy G= gravity constant of 32. A 416 Rigby was around 18. This energy is the figure most often given in books and magazines. recoil is – 8. 5 Creedmoor vs a. Recoil is a result of bullet weight, velocity and gun weight. Velocity: 2,500-2,910 ft/s; Energy: 2,820-4,042 J; Approximate Cost Per Round: 60 cents to $1. Lighter powder charges help in reducing recoil velocity. 55 ft/s (5. ) 8 pounds: 20. 45 recoil as measured might be as low as it is because of the redistribution of some of the recoil energy into linear slide movement. 5. , which translates to a 17. 4. 8 lbf•s. Many manufacturers and magazines have tried to quantify recoil reduction. If you are assaulted by a grizzly bear wearing a bullet proof vest and driving a '52 Buick, a . 45 caliber gun and a 9mm having the same energy but the . 5 Creedmoor is a very mild recoiling cartridge. 19fps: Free Recoil Energy: 34. The recoil might play a role in accuracy, especially for younger or less experienced shooters, but for the majority, we don’t think the increased recoil energy generated by the 6. 44 Magnum that weighs under 3-pounds. 380 ACP against that of the 9mm. With this data you can estimate the felt recoil of a specific firearm and cartridge. of free recoil through the same eight-pound gun. With a full magazine, the additional weight will mitigate it some. 5 ⋅ [ ( m p ⋅ v p ) + ( m c ⋅ v c ) 1000 ] 2 / m g u {\displaystyle E_{tgu}=0. That’s a lot. Post Dec 13, 2002 #3 Recoil: The added muzzle velocity means more recoil for the shooter. Some short-recoil–operated firearms, such as the German MG 42 and MG 3, use a mechanism at the muzzle to extract some energy from the escaping powder gases to push the barrel backwards, in addition to the recoil energy. Recoil Technology provides greater consistency, distance and trajectory control. We’ll use a total rifle weight of 8 pounds as our standard and use Winchester’s factory bullet weights and muzzle velocities. 38 special smith & Wesson revolver with weight 1. 308: Energy and Velocity As a general rule, the more kinetic energy is driving the bullet toward the target, the more accurate and deadly it will be. 1. Felt recoil seems to be the greatest obstacle to split times. That slide is taking some of the force and translating it into a moment going straight back, which delays the timing of the delivery of the recoil force until the slide comes to rest in the rearmost position. In other words, you simply square the velocity of recoil, which is easily calculated when we know the weight of the bullet and powder charge and its velocity when exiting from You can pencil out recoil’s kinetic energy using this formula: KE = MV2 / GC, where M is the rifle’s mass and V its velocity. 308-inch bullet to enter the rifling at a consistent angle, as Quinlen explains it. Both calibers are excellent defensive options with similar ballistic performance. 2 ft•lbs Recoil Impulse: 4. Compare the recoil of a Glock 17 and a Glock 20 with the AR Pistols. 357 Magnum in general has higher muzzle velocity . That rifle/load combination had a recoil velocity 25 percent more than a . It affects both muzzle rise and sharpness. 5 Creedmoor 120 gr. Some people hate the recoil of full load 3" 12-ga slugs, you know, those nasty 350-400 grainers being pushed at 1800+ fps. 50 Browning Machine Gun round. 5 lb Bullet Weight: 350. Free recoil energy in (ft/lbs) = 6. While recoil energy determines how hard the blow to the shoulder feels, recoil velocity determines how abrupt the blow to the shoulder feels. Out of that 6. 94 foot pounds of recoil velocity. 02 foot pounds of free recoil and 8. . We’ve had quite a discussion on this subject, and we also decided, by a unanimous decision, to add the following advice to help you to interpret the following table. 6 foot-pounds 300 Win. , Np 237 in the decay of Am 241, receives a recoil energy E due to conservation of momentum, ME = mE α, hence typically ~ 100 keV (91 keV in the decay of Am 241). 88 ft per sec 9 lb gun = recoil energy 29. It makes a world of sense. . Because it has an extended case, which means more propellant behind the bullet, the . 5 CM rounds are going to influence a single shot for most shooters. of the gun we can calculate the recoil velocity of the gun. as the prime consideration in muzzle energy is speed then the faster projectile will initially have more energy and recoil, consider however the lighter projectile will also lose its energy much faster than a heavier projectile. A 450/400 Nitro around 16. claimed 20ft/s. 8-pound rifle, that’s almost 40 ft-lb of recoil energy! However, when it comes to recoil, recoil velocity also matters. 460 Weatherby Magnum with a 500 gr bullet, a velocity of 2530, and a 116 grain charge, fired from a 10 pound rifle will have a muzzle energy of 7110 and a recoil energy of 94. 2. Mag. If the kinetic energy is the same, then a shorter duration and higher peak acceleration will move the rifle less because with a constant resistance to movement, movement is dictated by the velocity of the rifle, and the velocity of the rifle due to that acceleration increases exponentially with time. What is Recoil? (Warning: Contains Science) Recoil boils down to Newton’s first and third laws of motion. It does the calc with four inputs: Bullet weight (grains), Bullet Velocity (fps), Powder Weight (grains), Total gun weight (pounds). While free-recoil energy can be calculated using gun weight, velocity and weight of the ejecta (among other smaller variables), it The . 53 Some folks argue that free-recoil technique can result in a loss of muzzle velocity (around 20 fps) versus preloading a bipod. Since the energy goes up, that means the velocity goes up. 38 special bullet if it were travelling at 580ft/s after being discharged from a . 25 for match/hunting ammo. Millsy. 95 fps =13. . 380) is a stronger recoil, lowering overall accuracy in rapid-fire situations. Recoil limitations set by TOP 3-2-504 for shoulder-fired weapons. 375 H&H and onyl slightly more than 30-06. There are lots of negative (reducing) contributors: gun weight, recoil spring, gas venting, etc. Pair the lesser recoil energy with the weight of a full- or mid-sized pistol, and handling will prove to be comfortable and pleasant when shooting the 9mm. One of the problems you will run into is that you might not actually get the velocities that are listed in the reloading tables. The cartridge holds a bullet the same diameter as the 9mm (. Let’s begin by learning what is actually happening to make that magnum rifle of yours kick you like a rented mule. 5 N·s); Recoil velocity of 17. So, velocity is important because it drives the bullet. If you change either or both of these you will change the recoil force. 45 is great for striking large areas and creating large wounds. 5x the bullet velocity(due to the much lower temperature of the barrel air, and the expansional cooling of the leaked gases) the amount of kinetic energy(38. 078 m s. A stout load, too. 45x39 recoil vs . I'm not recoil sensitive, but I find that with lower recoil 1 oz. 6 lbf•s, and the 308 would be 2. lbs. The shaft is redirecting the energy to the ball and is also transferring stored energy from the golfer to the ball. com/calc/recoil. Comparing Recoil. . Reduced velocity loads will lower recoil. 308 Vs 30-06 review, you will come to know the differences of these 2 popular cartridges regarding size, ballistic, recoil, flexibility If you run the data for the lightweight 308 vs the 14 lb 6. of muzzle energy. . 1. 05j) available to work against the brake relative to the recoil forces is miniscule to say the least, especially compared to the 40+gn of gases Recoil is a function of action/reaction. lbs. and a recoil energy of 16. The 9mm cartridge also delivers less felt recoil than similar calibers, While a . 270 Win (130 grain) 8 pounds: 16. 8 After you input the necessary data such as the bullet weight, bullet velocity, powder charge weight, and the firearm weight it will output the recoil impulse, recoil velocity, and the recoil energy of the firearm. 35 Whelen load pushes a 200-grain bullet to just a shade more than 2,900 fps. 308 Winchester. The Hornady Superformance . The velocity number goes back to the acceleration of the bullet in the PRESSURE equation above. 8 ft. All other things being equal, a lighter gun will have more recoil velocity and more recoil energy. The primary factors are: Bullet weight Charge weight Muzzle velocity Gun weight With those four variables having numbers assigned, free recoil energy and velocity can be calculated. The unique composite construction creates a higher damping rate equating to better feel and less stress on joints in the hands, wrists and elbows. X Where K is the spring rate X is the deflection (squared in this formula) Home; Download the #HAAB Media Kit; 2018 Blog Bootcamp: THE AUDIO / VISUAL REVOLUTION First of all, there is no such thing as a Forster slug. The difference is noticeable enough that I'm planning on shifting completely to 1 oz. lbs. 5-foot pounds of energy. 452 inches (11. You are sacrificing power for recoil. 1. Conventional wisdom says that maximum comfortable recoil levels, for most shooters, is 15 foot pounds of free recoil energy and something less than 15 feet per second of recoil velocity. 243 Winchester. As you probably already know, there are two main components of recoil, recoil energy and recoil velocity. ) 8 pounds: 20. ES = Enhanced Stability for more control and feel ‰ۢ Stiffer mid and butt produces better shot It's velocity far more than weight that makes recoil, the same way velocity affects muzzle energy more than weight or caliber. The recoil velocity is typically the velocity of body 2 after the release of body 1. A. Two different loads could produce the same energy in the same gun, but feel very different due to recoil velocity, what some characterize as a push rather than a kick. 18 ft lbs Ft-lbs is a measure of energy not force. The revolvers were different sizes and weights and the four loads ranged from a light-recoiling standard pressure . The Smith & Wesson Model 340 PD 357 Mag revolver with a 2 inch barrel and made of Scandium and Titanium is extremely light at 0. But this doesn’t mean the . 30-06 Springfield and slightly more than a. 29ft-lbs: 27. A stiffer recoil spring will decrease the recoil generated during stage 1, because a stiffer spring will absorb more of the slide's energy. 223 recoil And now plug this info into the recoil calculator and we get a recoil velocity of 8. IE: For the same muzzle velocity the weight of the powder can have a significant impact on recoil. CMP Forums > CMP General > > CMP General > . . Accordingly, neither the Institute nor those responsible for the preparation of this or similar drawings or data sheets make any representation or warranty, or assume any responsibility with An increase in bullet weight combined with a reduction in muzzle velocity will yield a lower muzzle energy, and therefore reduced recoil (from a physics perspective - not perceived recoil perspective). , a recoil impulse of 2. Gun recoil actually has two parts: primary recoil from the escaping bullet and secondary recoil from the escaping gas behind the bullet. 07 fps 24. recoil energy vs recoil velocity
