7.62×45mm vz. 52

The '''7.62×45mm vz. 52''' cartridge is fired by the Czech vz. 52 rifle, vz. 52 and ZB-530 light machine gun. The round was later dropped from use when the Czech converted to the standard Warsaw Pact round, the 7.62×39mm (fired by vz. 52/57 rifle and vz. 52/57 light machine gun). Its ballistics and energy are slightly higher than that of the 7.62×39mm M43 cartridge.
