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.

1. Shaped propellant grains in the form of a propellant charge having a bulk density in the range of 0.550 to 0.750 grams per cubic centimeter, the propellant grains comprising a propellant composition for use in modern in-line muzzleloaders, wherein the propellant composition comprises: a) from about 70 to about 90% by weight of a cellulose-based organic fuel;b) from about 5 to about 30% by weight of a non-azide, nitrogen-containing, solid primary organic oxidizer; andc) from about 0.5% to about 10.0% by weight of a mineral-based secondary nitrate, perchlorate, chlorate or peroxide oxidizer, wherein, when used in said modern in-line muzzleloaders the products of combustion are substantially-completely gaseous, with the proviso that the propellant composition excludes nitroglycerin. 2. Shaped propellant grains in the form of a propellant charge having an energy per unit volume in the range of 400 to 700 calories per cubic centimeter, the propellant grains comprising a propellant composition for use in modern in-line muzzleloaders, wherein the propellant composition comprises: a) from about 70 to about 90% by weight of a cellulose-based organic fuel;b) from about 5 to about 30% by weight of a non-azide, nitrogen-containing, solid primary organic oxidizer; andc) from about 0.5% to about 10.0% by weight of a mineral-based secondary nitrate, perchlorate chlorate or peroxide oxidizer wherein when used in said modern in-line muzzleloaders the products of combustion are substantially-completely gaseous, with the proviso that the propellant composition excludes nitroglycerin. 3. Shaped hollow cylindrical propellant grains having: a) a length in the range 0.030 to 0.200 inch, b) a diameter in the range 0.040 to 0.070 inch, and having c) a coaxial opening there through having a wall grain thickness in the range 0.008 to 0.016 inch, the propellant grains comprising a propellant composition for use in modern in-line muzzleloaders, wherein the propellant composition comprises: a) from about 70 to about 90% by weight of a cellulose-based organic fuel;b) from about 5 to about 30% by weight of a non-azide, nitrogen-containing, solid primary organic oxidizer; andc) from about 0.5% to about 10.0% by weight of a mineral-based secondary nitrate, perchlorate, chlorate or peroxide oxidizer, wherein, when used in said modern in-line muzzleloaders the products of combustion are substantially-completely gaseous, with the proviso that the propellant composition excludes nitroglycerin. 4. The shaped hollow cylindrical propellant grains as claimed in claim 3 which are coated with graphite. 5. The shaped hollow cylindrical propellant grains as claimed in claim 3 having: a) a length of about 0.058 inch,b) a diameter of about 0.050 inch, andc) a coaxial opening there through having a wall grain thickness of about 0.012 inch. 6. The shaped hollow cylindrical propellant grains as claimed in claim 5 which are coated with graphite.
