The 5.6×39mm, also known in the U.S. as .220 Russian, is a cartridge developed in 1961 for deer hunting in the USSR.[3] It fires a 5.6mm projectile from necked down 7.62×39mm brass. While it originally re-used 7.62x39 cases, once it became popular enough commercial ammunition started being manufactured, both in the USSR and in Finland.[4] [5] When it was introduced to the United States by SAKO it was stamped .220 Russian. Lapua later changed the designation to .220 Russian for the American market as well.[6] [5]

Soviet 5.6×39mm cartridges were loaded with smokeless powder VT (винтовочный пироксилиновый порох ВТ), as well as Soviet 7.62×54mmR and 9×53mmR hunting cartridges.[7] It is the parent case for the .22 PPC, 6mm PPC, and the 6.5mm Grendel cartridges.[6]
