308 Winchester

The .308 Winchester is a rimless, bottlenecked rifle cartridge and is the commercial cartridge from which the 7.62×51mm NATO round was derived. The .308 Winchester was introduced in 1952, two years prior to the NATO adoption of the 7.62×51mm NATO T65. Winchester branded the cartridge and introduced it to the commercial hunting market as the .308 Winchester. The .308 Winchester is one of the most popular short-action hunting cartridge worldwide. The relatively short case makes the .308 Winchester especially well-adapted for short-action rifles. [Wikipedia]
