  • Methods of preparing nitrocellulose based propellants and propellants made therefrom
    Patent number: 10801819
    Abstract: Methods of preparing propellant compositions for power loads and firearms that include providing pre-shaped particle sized starting material, shaped consistent with a desired final propellant product shape, and thereafter nitrating and stabilizing the pre-shaped starting material using boiling stabilization processes. The resulting nitrated propellants of the methods reliably exhibit complete stabilization, high nitrogen substitution, high shelf life and acceptable ballistic performance.
    Type: Grant

  • Advanced muzzle loader ammunition
    Patent number: 10254092
    Abstract: A muzzle loaded ammunition round having a bullet and a consumable cartridge case. The cartridge case is hollow and is filled with at least one propellant composition, the cartridge case being constructed from a consumable material, such as foamed celluloid. The bullet is commonly engaged to the propellant composition at least via the cartridge case, the propellant composition having a charge weight.

  • Muzzle loader powder increment using celluloid combustible container
    Patent number: 8881634
    Abstract: An encapsulated propellant charge comprised a sealed combustible container comprised of a consumable material and having a substantially cylindrical shape. The sealed combustible container comprises a top wall, a bottom wall, and a side wall therebetween. The top wall, the bottom wall and the side wall define a chamber; which contains a propellant composition.
