8mm kurz

The 7.92×33mm Kurz (designated as the 7.92 x 33 kurz by the C.I.P.) is a rimless bottlenecked intermediate rifle cartridge developed in Nazi Germany prior to and during World War II, specifically intended for development of the Sturmgewehr 44 (assault rifle). The ammunition is also referred to as 7.9mm Kurz (German: Kurz meaning "short"), 7.9 Kurz, 7.9mmK, or 8×33 Polte. The round was developed as a compromise between the longer 7.92×57mm full-power rifle cartridge and the 9×19mm Parabellum pistol cartridge, and is the first mass-used intermediate cartridge (German: Mittelpatrone) in the world.
