The PRB covers the role of propellant gases in recoil, and measures effectiveness of muzzle brakes. In the typical examples above, as the bullet weight goes up the muzzle velocity (MV) goes down; but the recoil energy and recoil velocity both continue to go up. Even keeping the magazine full of ammunition when firing will make a difference. the figures were 1,187 fps and 1,331 fps. Although both mass and velocity contribute to the muzzle energy, the muzzle energy is proportional to the mass while proportional to the square of the velocity. One area where muzzle velocity plays less of a role is in recoil. Recoil: A shorter barrel usually means more recoil, as the blast created when the bullet exits the barrel is closer to the rest of the gun, and thus, closer to the shooter. 74 rr*).
