The .30 Kurz is made by shortening the .30-06 or .308 Winchester to 1.290 inches. This produces a short cartridge very similar to the German 7,92 Kurz assault rifle cartridge of WWII. The idea originated in the 1960’s and there are other versions of this cartridge. It is intended for use in modified M1 carbines and is the same length as the .30 Carbine case. The name can be a bit misleading. There is an older cartridge, 30 COURT (Court = French, Kurz = German), but it is based on the 30 M1 Carbine case and was loaded by RWS.
