A propellant load arrangement for a large caliber ammunition cartridge case accommodating a ballistic projectile includes a plurality of relatively flat shaped segments of propellant assembled face to face in an ordered arrangement. The faces of the segments of the arrangement are optionally parallel or perpendicular to the longitudinal axis of the cartridge case and essentially occupy the entire available propellant volume of the case. The outer peripheral geometry of each segment of the ordered arrangement is shaped to match the corresponding cartridge casing interior geometry and each segment of the ordered arrangement also has a shaped central interior recess opening as required of a geometry matching the corresponding geometry of any interfering internal cartridge part and any projectile geometry present. Relatively cool-burning segments can be combined with relatively hot-burning segments in stratified arrangements to provide a cooler boundary layer and reduce tube erosion.

[ We claim:] [1.] A propellant load arrangement for a munition cartridge having a longitudinal axis and having an internal volume for accommodating a ballistic projectile and propellant material comprising:(a) a plurality of relatively flat shaped slab segments of propellant material assembled face to face in an ordered arrangement, the faces of the segments of the arrangement being generally parallel to the longitudinal axis of the cartridge case and generally configured to occupy the available propellant volume of the cartridge; and(b) each of said slab segments of the ordered arrangement further having an outer peripheral geometry being generally shaped to accommodate the corresponding cartridge casing interior geometry and each of said slab segments of the ordered arrangement, where necessary, further having a shaped central interior recess opening of a geometry accommodating the corresponding geometry of any interfering internal cartridge element and any required projectile exterior geometry.
