The .303 British (designated as the 303 British by the C.I.P.[2] and SAAMI[3]) or 7.7×56mmR, is a .303-inch (7.7 mm) caliber (with the bore diameter measured between the lands as is common practice in Europe) rimmed rifle cartridge first developed in Britain as a black-powder round put into service in December 1888 for the Lee–Metford rifle. In 1891 the cartridge was adapted to use smokeless powder.[4] It was the standard British and Common wealth military cartridge from 1889 until the 1950s when it was replaced by the 7.62×51mm NATO.[2]
