This cartridge was developed during late 1940s and early 1950s by Czhechoslovak military experts, and originally was chambered in just two weapons – Vz.52 semi-automatic carbine and Vz.52 light machine gun. A true assault (automatic) rifle for this cartridge was still in the works when Czhechoslovak army was forced (under Warsaw pact standartisation agreements) to replace this round with slightly less powerful 7.62×39 M43 round of Soviet origin.
Today thsi round is obsolete and its production has long been completed.
