12,7 x 108 mm

12,7 x 108 mm –Soviet cartridge for large-calibre machine guns introduced into the Red Army's arsenal in 1934, inspired by the English 12.7 × 81 mm and the American .50 BMG (12.7 × 99 mm NATO). Initially designed for DK and DShK machine guns, it later became the standard cartridge for a wide range of large-calibre machine guns and rifles. In the 1950s it became the standard for this type of weapon for the Eastern Bloc countries. It is stamped with the standard Soviet pattern, the factory number at 12 o'clock, the year of manufacture at 6 o'clock and either a star at 3 or 9 o'clock - the brass  cartridge case.
