.308 Winchester is the commercial name of a centerfire cartridge based on the military 7.62x51mm NATO round.
Two years prior to the NATO adoption of the 7.62x51mm NATO T65 in 1954, Winchester (a subsidiary of the Olin Corporation) branded the cartridge and introduced it to the commercial hunting market as the .308 Winchester.
