Abstract

Un magasin pour arme à feu comprend un corps annulaire (1) consistué essentiellement d'une première bague (10) et d'une deuxième bague (20). Le diamètre extérieur de la deuxième bague est inférieur à celui de la première bague (10), de sorte qu'un gradin circonférentiel (5) est présent à la périphérie du corps annulaire (1). Un certain nombre de premières chambres (15) équidistantes sont ménagées axialement dans la première bague et abritent des corps de charge propulsive (4). Des deuxièmes chambres (25) équidistantes s'étendent axialement dans la seconde bague et abritent des corps de projectile (3). Dans une position de chargement donnée, un corps de projectile (3) peut être transféré radialement et un corps de charge propulsive (4) peut être transféré axialement depuis le corps annulaire (1) simultanément, pour aboutir dans des alésages correspondants d'une chambre de cartouche dans le carter, prévu à cet effet, d'une arme à feu.
