This invention relates to a rifle cartridge magazine for carrying and automatically feeding a plurality of rifle cartridges one at a time sequentially into the breech of a rifle characterized by a housing open at the top containing an arcuately-curved cartridge compartment therein sized and shaped to define a track effective to engage the front and rear ends of each cartridge and guide same into the breech, a pair of ribs depending from one face of the housing and extending into the cartridge compartment in spaced parallel relation to one another defining rails paralleling the front and rear ends of the track located in between the latter, a follower provided with spaced parallel slots extending transversely thereof on one side for riding the rails, the aforementioned slots and rails cooperating with one another to maintain the follower in substantially perpendicular relation to the track ends, and at least one constant force coiled clock spring having one end pivotally secured adjacent the open upper end of the housing and its other end terminating in a free-standing coil hanging down inside the cartridge compartment, the follower having a pocket formed therein opening toward the face of the housing to which the spring end is secured, such pocket being sized to receive the coiled end of the latter, and the spring being operative with its coiled end thus retained in the pocket to pull the follower upwardly along the rails with a relatively constant force thereby pushing the cartridges ahead thereof into position the enter the breech.
