An externally powered twin-barrel shuttle gun which has a shuttle having two firing chambers. The shuttle linearly moves between two positions so that the firing chambers are alternately fed a round of ammunition and discharged. The feed system has a pair of augers, each with a helical groove therein which receives a round of ammunition which obtains a dwell position on the zero pitched section of the grooves. A ramming system rams a round of ammunition to the firing chamber aligned therewith and simultaneously ejects any spent cartridge through a forward aperture in the housing. The spent cartridge is frictionally engaged by an axially aligned acceleration belt which quickly withdraws the spent cartridge from the firing chamber and accelerates it onto a deflection cam.
