From Iron Man's Iron Manual Page 25:

As the magazine revolves, rounds are fed into a high-speed round transfer device that positions the round in the chamber just as the bolt moves around it and detonates the charge. Since there is no case to eject, the action is very fast and since the entire weapon is computer controlled, one can select any rate of tire from one round per second up to 1,000.
