7.92x33mm kurz

The 7.92×33mm Kurz (designated as the 7,92 x 33 kurz by the C.I.P.) is a rimless bottlenecked rifle cartridge developed in Nazi Germany prior to and during World War II. The ammunition is also referred to as 7.9mm Kurz (German: Kurz meaning short), 7.9 Kurz, or 7.9mmK, or 8×33 Polte. It was specifically intended for development of an automatic carbine (assault rifle). The round was developed as a compromise between the longer 7.92×57mm rifle and the 9×19mm Parabellum pistol rounds, and is known as an intermediate cartridge (German: Mittelpatrone).
