 These were determined to be less than ideal, as the recoil of full-power rifle cartridges caused the weapon to be uncontrollable in full-automatic fire.They then developed an intermediate-power cartridge round, which was accomplished by reducing the power and the length of the standard 7.92×57mm Mauser rifle cartridge to create the 7.92×33mm "Kurz" (Short) cartridge.A selective-fire weapon was developed to fire this shorter cartridge, eventually resulting in the Sturmgewehr 44, later translated as "assault rifle" (also frequently called "machine carbines" by Allied intelligence, a quite accurate assessment, in fact).
