Cartridge case member with a combustible tube, ammunition with a semicombustible cartridge case incorporating this member and process for filling this ammunition. The present invention relates to the field of combustible ammunition and relates more particularly to that of dart-shell semicombustible ammunition. The invention relates to a cartridge case member (3) with a combustible tube (6) comprising a bottom (7) which has a central opening (8) and a side opening (9). A hollow component (4) enters the said member (3) through the central opening (8) without obstructing the side opening (9). This hollow component (4) is a shell of revolution which comprises, over its entire height, a central cavity on the wall of which are arranged means (18) for fastening a separate component. The invention also relates to semicombustible ammunition (1) comprising a member (3) according to the invention. Finally, the invention relates to a process for assembling such ammunition, a process according to which, after the ignition tube (34) and the shell have been fastened to the member (3), the latter is filled with powder by virtue of the side opening (9) and the metal base (2) is fitted only afterwards by snapping on.
Ammunition comprising a semi-combustible cartridge case, a shell and an ignition tube, said semi-combustible cartridge case comprising a combustible tube having a bottom which has a central opening, said bottom including a separate side opening beside and spaced from said central opening, a hollow component mounted about said central opening and without obstructing said side opening, said hollow component comprising a hollow cavity along its entire length bounded by an internal wall, said internal wall having means for fastening a metal base inside said central cavity, said means for fastening comprising two substantially parallel rectillinear openings disposed on each side of an axis of said hollow component in the same plane and perpendicular to said axis and two resilient bars, disposed in said openings, said ammunition comprising a metal base carrying a central hollow ferrule with said ferrule projecting into said central cavity of said hollow component and which includes cooperating means for cooperating with said two resilient bars so as to receive said bars to retain said ferrule and said base in said central cavity.
