Overview
The 7.62×39mm round is a rifle cartridge of Soviet origin that was designed during World War II. It was first used in the RPD but is more widely used in the SKS and AK-47 pattern rifles. 7.62×39mm ammunition functions in temperatures ranging from –50 to +50 C and is used for sporting and hunting through bolt-action and semi-automatic rifles, carbines, or pistol-length platforms. The cartridge keeps its qualities under various climatic and weather conditions independent of the season and at a temperature. This round sports a steel case. It is lacquered to guard it against the elements and smooth it out for easier extraction from a semi-auto and sealed at the neck and mouth for even greater resistance to moisture infiltration.
