The 7.62x54mmR is a Russian rifle cartridge dating back to 1891. Originally designed for the bolt-action Mosin-Nagant rifle, it was used during the late Tsarist era and throughout the Soviet period, in machine guns and rifles such as the SVT-40. This cartridges remains one of the few standard issue rimmed cartridges still in military use.[1]
The American Winchester Model 1895 was also chambered for this cartridge per a contract with the Russian government. The 7.62x54mmR is still in use by the Russian military in the Dragunov and other sniper rifles and some modern machine guns such as the PKM. The round is colloquially known as the "7.62 Russian," although the "R" actually stands for "rimmed". The name is sometimes confused with the "7.62 Soviet" round, which refers to the 7.62x39mm cartridge used in the SKS and AK-47 rifles.
