Dual ammunition transfer mechanism

A dual ammunition transfer mechanism includes a pair of ammunition round feed conveyors for selectively conveying the same size but different types of rounds toward a pivotal round selector finger. One conveyor is stopped while the other conveyor is driven causing the rounds therein to move past a round deflector finger which guides the rounds between driven star wheels and a Z-shaped feeder. A round kicker drives rounds one at a time into a slot in a disc rotating at high speeds and having camming surfaces therein which cooperates with a round lifting finger which momentarily enters the slot and stops the round while the disc continues to rotate while camming the round out of the slot at a rate of up the 400 rounds per minute.
