Web29 jul. 2016 · Rifling works by spinning the projectile about its axis, causing gyroscopic forces that spin-stabilize it throughout its flight; tighter rifling will spin a bullet faster, while looser rifling will spin a bullet slower. WebThe spin rate of the bullet depends on the twist rate of the rifling. The twist rate and velocity of the bullet provide RPM which helps bullet to stabilize. The RPM of velocity can be calculated as. Bullet RPM = Muzzle velocity x 720 / Twist Rate. Therefore, bullets spin when shot from a rifle or handgun because barrel rifling causes this spinning. earth retaining structures ppt
