The automatic cartridge feeder can receive a cartridge through the priority slot regardless of the condition of the cartridge magazine. In an automatic mode, cartridges are taken sequentially from the magazine and are processed. Any cartridge placed in the priority slot by an operator will be processed immediately after any in-progress cartridge processing. In an accumulate mode, cartridges are received through the priority slot for processing and are returned in sequence to an empty cartridge magazine.
