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. The magazine has an arcuate shape with one end wall having a portion defined by a radius of about 5.29 inches. Three rails are positioned on the upper portion of one side wall. Rails and baffles are configured to avoid or reduce interference of debris or wax build-up. A method for making the magazine by injection molding parts to produce the desired rail structure is included.
