Abstract: A combustible cartridge assembly is described. The assembly of one embodiment includes a projectile, a body having a first end portion coupled to the projectile and a second end portion opposite the first end portion. The body is made of a combustible material configured to be consumed upon firing the ammunition round assembly. A sleeve is at least partially contained within the base. The sleeve has a free end portion radially to adjacent to and coupled to the second end portion of the body. The sleeve and the body defines an interior area configured to contain a combustible propellant. A non-combustible base at least partially is coupled to the sleeve and is adjacent to the second end portion of the body.
