Grooves formed in the bore of firearm barrel to impart rotary motion to a projectile.

1. (n.) Spiral grooves formed into the bore of a gun barrel, which cause the bullet to spin upon firing, thus stabilizing it much like a thrown football. Rifling may be cut, swaged, or forged into the barrel. 2. (v.) The process of forming the rifling in the bore.

Parallel spiral grooves cut into the bore of a firearm, which impart spin to the projectile as an aid to accuracy and consistency of strike.

The spiral grooves in the bore of a rifled firearm. The rotation they impart to a projectile stabilizes in a flight

the cutting of spiral grooves on the inside of the barrel of a firearm

Rifling is found on the inside of the barrel tube of most rifles and pistols. It is made up of a a spiral shaped series of grooves. When a bullet begins its path down the barrel, it threads itself into the rifling, which causes the bullet to begin spinning. The spinning bullet is more stable.

The groves cut in a spiral into the bore of a handgun or rifle barrel. The uncut higher spaces between the groves are called lands. Rifling makes the bullet spin as it travels down the bore and when the bullet is in flight this spin makes it more accurate and travel faster.

Grooves in the bore of the barrel that impart spin to the bullet to improve its stability during its trajectory.

The spirally cut grooves in the bore of a rifle or handgun. The rifling stabilizes the bullet in flight. Rifling may rotate to the left or the right, the higher parts of the bore being called lands, the cuts or lower parts being called the grooves. Many types exist, such as oval, polygonal, button, Newton, Newton-Pope, parabolic, Haddan, Enfield, segmental rifling, etc. Most U.S.-made barrels have a right-hand twist, while British gunmakers prefer a left-hand twist. In practice, there seems to be little difference in accuracy or barrel longevity.

Twisted Lands and Grooves are placed into a barrel to impart spin on the bullets that pass through it.

A continuous spiral groove cut along the inside surface of the barrel to improve the accuracy and range of the bullet by giving it a spin as it leaves the barrel. Rifling uses the same principle that makes a football go straight when thrown correctly. Rifles (by definition) always have rifling, handguns typically do, and shotguns rarely do. .41 caliber rimfire ammunition

Parallel spiral grooves cut or impressed into the bore of rifles and pistols in order to make the bullets spin, insuring steady, point on flight to the target.

Helical or spiral grooves cut into the inside of the barrel surface to cause the bullet to spin in a rotary or spiraling motion causing the projectile to travel with greater stability. The cut-away portions of the rifling are called grooves while the uncut portions are called lands.

Spiral grooving in the bore of a firearm that is used to spin-stabilise the projectile and thus improve its accuracy after leaving the barrel. Rifling can be either clock, or anti-clockwise in direction and can have either an even, or an odd number of grooves. Pistols can and usually do have rifled barrels, the system is not unique to 'rifles'.

Spiral grooves in a gun's bore that spin the projectile in flight and impart accuracy. Rifling is present in all true rifles, in most handguns and in some shotgun barrels designed for increasing the accuracy potential of slugs( a slug is a single projectile rather than the more common "shot".)

The grooves cut into the bore of a firearm to impart rotary motion to a bullet for gyroscopic stabilisation.

Spiral grooves cut or impressed into the bore of rifles and pistols in order to make the bullets spin, insuring stable flight to the target. See grooves and lands.
