The present invention relates to a propellant charge which uses a high packing density propellant grain which provides for very nearly full utilization of the volume of a cartridge, case, or weapon propellant chamber. The present grain design permits nearly full utilization of the propellant chamber without requiring the necessity of vibration or compaction after assembly. The present device permits passage of gases through the propellant charge so that the resultant ignition and thrust forces are substantially smooth and surge free.
