Abstract
A high capacity box magazine is provided. A plurality of nested followers may be adapted to nest one within another and a plurality of springs may be configured to nest one within another to facilitate the advancement of cartridges within the box magazine to a firearm. A spring cup or cups may be used to nest additional springs that work in series and are nested within each other to further reduce the required height of the springs. The reliability of a conventional lower capacity box magazine may be maintained or exceeded without requiring significantly greater length in order to accommodate the increased capacity. The high capacity box magazine typically requires less frequent magazine changes than conventional lower capacity box magazines.
