7.62×45mm
The 7.62×45mm (designated as the 7,62 × 45 by the C.I.P.) is a rimless bottlenecked intermediate rifle cartridge developed in Czechoslovakia. It is fired by the Czech Vz. 52 rifle, Vz. 52 light machine gun, and ZB-530 machine gun. The cartridge was later dropped from use when the Czech converted to the standard 7.62×39mm Warsaw Pact cartridge of the Soviet Union. Its muzzle velocity and muzzle energy are slightly higher than that of the 7.62×39mm cartridge, and is on par with the .30-30 Winchester cartridge, with equivalent projectiles.

==Cartridge dimensions== The 7.62×45mm has a 2.79 mL (43.1 gr H2O) cartridge case capacity. The exterior shape of the case was designed to promote reliable case feeding and extraction in bolt-action and semi-automatic rifles and machine guns alike, under extreme conditions.
