Shotgun Recoil Table: 12-gauge vs 20-gauge vs .410 - Backfire V This means This reaction force is known as recoil, and it can be felt when the firearm is held. Grain Weight vs Felt Recoil | Hi-Point Firearms Forums The angle at which the bullet leaves the barrel above the aim angle is then given by: Before the projectile leaves the gun barrel, it obturates the bore and "plugs up" the expanding gas generated by the propellant combustion behind it. For example, a gun that is said to "kick like a mule" is going to be approached with trepidation, and the shooter may anticipate the recoil and flinch in anticipation as the shot is released. #10. RE = a constant / effective mass of the firearm. rifle for a powerful Magnum cartridge like the .300 WSM and the result With this data you can estimate the felt recoil of a specific firearm and cartridge. All rights reserved. As mentioned elsewhere, if your friend's gun is 2# heavier, that could be the difference. Recoil is a familiar term and topic in this blog. Less weight to soak up recoil = more recoil. The impulse-momentum equations for systems of particles are particularly useful for (i) analyzing the recoil of a gun; and (ii) analyzing rocket and jet propulsion systems. The 7mm-08 Remington's recoil produces 14.88 ft-lbs of energy at a velocity of 10.68 fps. these do make a difference on what is considered heavy recoiling. Recoil: It's the Law Newton's third law explains the phenomenon of recoil, or "kick." When you fire a shotgun, it is going to jerk backward with the same force as everything that comes out of its barrel: propellant gasses, wad, shot/slug.
