What does rifling mean?
Rifling is the name for the spiral grooves cut inside the barrel of a gun and, by extension, for the process of cutting those grooves. As a projectile travels through a rifled barrel, the grooves impart spin to it. This spin tends to stabilize the projectile, improving its accuracy and resistance to unpredictable movement in flight. Rifling is therefore important in the manufacture of rifles, pistols, machine guns, and artillery pieces, and its twist, depth, and pattern can vary according to the intended projectile and weapon. The word is most often encountered in technical or historical discussions of firearms. Although the process can be described as rifling a barrel, the resulting feature is usually referred to simply as the barrel’s rifling. The term is neutral and technical rather than valorizing, and it should not be confused with riffling, which concerns moving through papers or another series of objects.
nounRifling is the system of spiral grooves cut into the bore of a gun barrel to give a projectile spin and improve its stability in flight. It can also refer to the process or technique of cutting these grooves.
- The spiral grooves cut into the bore of a gun barrel.
- The process or technique of cutting such grooves.
"The gunsmith carefully inspected the rifling before restoring the antique barrel."
"The rifling gives the bullet spin, improving its stability and accuracy."
"Modern manufacturing methods allow rifling to be cut to precise, computer-designed patterns."
Rifling is normally uncountable because it refers either to the grooves collectively or to the process of cutting them.
"Heavy wear had damaged the rifling near the muzzle."
Rifling turns a spinning projectile into a tiny, stabilized gyroscope.

Etymology of rifling
Rifling was formed in English from rifle with the noun-forming suffix -ing, in the sense of the grooves or spiraling cuts associated with a rifled barrel. Rifle was borrowed through French from rifler, meaning to groove or scratch, reflecting the original sense of cutting a barrel’s spiraling grooves. Related English words include riffle, from the same French root, and rifler, a person who rifles or searches through things.
