20" 308/7.62x51 Nitride FAXON Big Gunner Barrel AR10/LR308 Rifle Upper Assembly with 15" Rail and Competition Muzzle Brake
During the 1940s Winchester saw a market for a civilian model of the late T65 series designs and introduced the 308 in 1952. Since then, the .308 Winchester has become the most popular short-action big-game-hunting cartridge worldwide. The relatively short case makes the .308 Winchester especially well-adapted for short-action rifles. The .308 Winchester has slightly more drop at long range than the 30-06, owing to its slightly lower (around 30 metres per second (100 ft/s)) muzzle velocity with most bullet weights. Cartridges with significantly higher muzzle velocities, such as the 300 Magnum can have significantly less drop at long range, but much higher recoil. The relatively short case makes the .308 Winchester especially well-adapted for short-action rifles. When loaded with a bullet that expands, tumbles, or fragments in tissue, this cartridge is capable of high terminal performance.
