In some cases, rifling will increase the twist rate as the projectile travels down the length of the barrel, called a gain twist or progressive twist; a twist rate that decreases from breech to muzzle is undesirable because it cannot reliably stabilize the projectile as it travels down the bore. [3] [4] See more In firearms, rifling is machining helical grooves into the internal (bore) surface of a gun's barrel for the purpose of exerting torque and thus imparting a spin to a projectile around its longitudinal axis during See more For best performance, the barrel should have a twist rate sufficient to spin stabilize any bullet that it would reasonably be expected to fire, but not significantly more.
