Rifling is the term for helical grooves machined into the internal surface of a firearms 's barrel for imparting a spin to a projectile to improve its aerodynamic stability and accuracy. It is also the term (as a verb) for creating such grooves.

: the act or process of making spiral grooves. : a system of spiral grooves in the surface of the bore of a gun causing a projectile when fired to rotate about its longer axis. Examples are …

2022年3月11日 · Barrel rifling is the spiral grooves inside the barrel of a firearm that causes the bullet to spin. This spin imparts a gyroscopic stability to the projectile, which in turn improves the bullet’s accuracy.

2023年5月21日 · Rifling takes the form of one or more lands and grooves of differing widths, profiles, arrangements and twist (turn) rates. The spiral depressions in the bore surface between the lands are called...

2023年10月19日 · Rifling refers to the spiral (helical) grooves that are cut or swagged on the internal surface (bore) of a gun barrel, which helps impart the spinning motion to a bullet when it’s fired.

Rifling consists of spiral grooves cut into the inside of a barrel of a gun. [1] . It causes the bullet or projectile to spin as it flies through the air. This greatly improves the accuracy of the bullet over longer distances. [2] . The first muskets to use this technology were called rifles. [2] . Barrels are rifled using a left or right twist.

2017年5月15日 · The purpose of rifling is to impart a spin to a projectile as it is thrust through the air in order to stabilize it and allow it to be more accurate.

Savage 1920 .250-3000 (left); Kimber Montana .223. Obvious differences in the newer rifle are stainless steel, synthetic stock, optical sight. Not so obvious is the rifling twist — 1-14 in the Savage, 1-9 in the Kimber.

Rifling is the process of creating grooves inside the bore of a rifle, pistol and some shotguns. These grooves cause the projectile to spin as it moves down the barrel and exits the muzzle.

2016年6月24日 · 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.
