Abstract
Propellant compositions are provided herein for use in small arms cartridges. Such propellant compositions include a cellulose-based organic fuel, a non-azide, nitrogen-containing primary organic oxidizer and a secondary nitrate, perchlorate, chlorate of peroxide oxidizer. Preferably, such compositions are in the form of extruded shaped hollow cylindrical grains having dimensions that makes it loadable in a muzzleloader firearm or small calibre firearm cartridge case. Ignition grains are also provided for use alone or in a mixture with the propellant compositions. When used in a small calibre firearm or muzzleloader, the temperature of combustion is at a level that ensures substantially complete combustion of the fuel during firing so that the products of combustion are mostly gaseous.
