Abstract
An improved magazine wherein cartridges are loaded therein in two nested helical rows. Improvements further include a spring loaded feed lip bar which permits rapid loading and unloading of the magazine; a rod inside the drive spring in the magazine which prevents kinking and other undesirable operation characteristics of the main drive spring and which also permits the main drive spring tension to be released only when the magazine is not mounted on the cooperating gun; and a folding winder which is part of the magazine's rear end clutch and winder assembly which speeds winding of the spring.
