Abstract
A magazine is provided for housing a predetermined number of rim-fire cartridges in a double column configuration with minimal magazine width and length requirements. The magazine is configured so that the rims of the cartridges are automatically placed in a nested or staggered relationship when they are inserted and are maintained in that relationship as they move through the housing, so as to prevent cross over of the rims and jamming. The nested, side-by-side positional relationship of the cartridges in the magazine is changed to a single file relationship while the lateral force exerted on the cartridges is controlled and jamming caused by friction or deformation is prevented. A split follower device having two followers which are movable with respect to each other is provided to maintain an upward bias on the cartridges throughout their movement through the magazine.
