Title: Propelling material formed in strips for use in large caliber guns

Abstract: The invention provides an improved propellant system for firing projectiles in large caliber guns. Strips of energetic propellant are placed in the cartridge case so that the lengths of the strips are parallel to the length of the cartridge. Preferably, the strips are placed in a radially symmetric pattern. The strips provide passageways that allow ignition gasses to flow radially in the cartridge case and along the length of the cartridge case.
