A high energy ignitable composition provides a safe and easily handleable replacement for a low smoking or smokeless black powder. The composition is formed by intimately and homogeneously blending 6 to 15 weight percent potassium perchlorate, 45 to 55 % by weight nitrate-containing oxidizing agent, and 30 to 49 % by weight of organic acid fuel, such as ascorbic acid or erythorbic acid, or the sodium salts of these acids. These compositions can provide a heat of combustion in excess of 700 calories per gram, which includes a combustion gas volume of at least 280 cubic centimeters per gram. The ingredients of the composition are present in the form of primary particles having an average particle size of from 1 to 50 microns which have been compacted at a pressure of from 250 to 20,000 pounds per square inch. A consumable cartridge includes a molded cartridge case from the ignitable composition. |
