A rifle is a firearm designed to be fired from the shoulder, with a barrel that has a helical groove or pattern of grooves ("rifling") cut into the barrel walls.The raised areas of the rifling are called "lands," which make contact with the projectile (for small arms usage, called a bullet), imparting spin around an axis corresponding to the orientation of the weapon.
The Model 0000 rifle and Model 6000 carbine use a slower 305 mm (1:12 in) twist rate for the shorter and lighter American M193 bullet. Fabrique Nationale also offers semi-automatic-only Law Enforcement carbine versions: [citation needed] the Model 7030 with a 178 mm (1:7 in) rifling twist and the Model 6040 with a 305 mm (1:12 in) twist rate ...
The Remington 572 was introduced in 1954 as a successor to the Remington Model 121 as the M572A having the look and feel of the Remington 870 shotgun. Weighing in at 5 lbs., the rifle is a "hammerless" style, meaning the hammer is contained within the action and ejection is through the side.
Rifling of a 105 mm Royal Ordnance L7 tank gun Conventional rifling of a 90 mm M75 cannon (production year 1891, Austria-Hungary) Rifling in a GAU-8 autocannon. 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.
The maximum practical range [note 4] of all small arms and especially high-powered sniper rifles depends mainly on the aerodynamic or ballistic efficiency of the spin stabilised projectiles used. Long-range shooters must also collect relevant information to calculate elevation and windage corrections to be able to achieve first shot strikes at ...
The muzzle velocity of the carbine bullet was 1,150 feet per second. The 1884 model rifle generated 1525 ft lbs of energy at 100 yds, and 562.3 ft lbs of energy at 1,000 yards, with a maximum range of 3,500 yards.

The .408 Cheyenne Tactical (designated 408 Chey Tac (10.36×77mm) by the C.I.P.) [3] is a specialized rimless, bottlenecked, centerfire cartridge for military long-range sniper rifles that was developed by Dr. John D. Taylor and machinist William O. Wordman.
The SR-25 (Stoner Rifle-25) [1] is a designated marksman rifle and semi-automatic sniper rifle designed by Eugene Stoner and manufactured by Knight's Armament Company. [1] The SR-25 uses a rotating bolt and a direct impingement gas system. It is loosely based on Stoner's AR-10, rebuilt in its original 7.62×51mm NATO caliber.
