1. A consumable ammunition assembly, comprising:
- a projectile having a leading portion and a trailing portion;
a consumable cartridge body having a first end portion connected to the trailing portion of the projectile, and the body having a second end opposite the first end, wherein the body comprises approximately 55%-70% energetic material, approximately 20%-30% non-energetic structural fibrous material; and
8%-15% additives, and wherein the energetic material comprises approximately 90%-100% nitroguanidine and approximately 0%-10% other energetic material different than nitroguanidine;
a non-combustible base connected to the second end portion of the body and forming a closed bottom of the ammunition assembly; and
a propellant bed contained in the body and intermediate the projectile and the base.
