ABSTRACT:
A cartridge assembly is provided, in one embodiment, comprising a combustible casing with an open forward end and an open breech end, enclosed at the breech end by a thin metal stub casing, a projectile assembly mounted in the forward end, an igniter assembly, a resilient obturator pop riveted to the casing, an annular sabot, and a plurality of flexible combustible priming tubes immersed in a propellant charge and extending the length of the casing. In another embodiment, the combustible casing comprises two separate casings joined together with fasteners, each casing having a set of flexible combustible priming tubes, an interface portion defined between the two where respective ends of combustible priming tubes abut. In both embodiments, the priming tubes combust rapidly producing complete ignition of the propellant charge and resultant stable projectile flight.
