Abstract
Magazine apparatus for accommodating propellant charges including a flat coilable metal strip having a plurality of holes extending transversely therethrough for accommodating insertion of cartridges. Cartridge holding collars are formed at each of the holes by bulging or plastically deforming the strip in the region of these holes so as to form a clamping seat spaced from the plane of the strip for clampingly engaging cartridges held at the strip. Various preferred embodiments include various cross-sectional configurations of the holding collars. The method of making the magazine apparatus includes forming the collars by a multiple-step bulging process wherein the last bulging steps is formed by the cartridges as they are inserted into position on the strip.
