    Abstract: An inline hammerless percussion firing system for muzzleloader firearms with a striker having a firing pin and a striker spring to linearly drive the firing pin forward. A cocking button compresses the striker spring. A pivoting retainer acts against a nut connected to the cocking button to hold the cocking button forward and keep the striker spring compressed. A sear acts to prevent the striker from moving forward until released by a two piece trigger system in which a trigger and trigger edge pivot relative to each other with lost motion before releasing the sear, allowing the trigger edge to move out from below a safety notch in the sear, where firing is prevented, to below a firing notch in the sear to prevent accidental discharges from impact. The cocking button can be released by an uncocking button. Releasing a barrel catch resets firearm to the initial safe position.

    Abstract: A clean burning premeasured compressed charge for use in black powder firearms as well as cartridges. The premeasured compressed charge is manufactured to have a substantially desired shape which facilitates improved flame propagation by the leading end wall and along the exposed sidewall surfaces of the compressed charge to result in a more complete and rapid burning of the compressed charge both from the leading end wall toward the trailing end wall and also radially inwardly from each one of the four sidewalls toward a center of the premeasured compressed charge. The premeasured compressed charge has a leading end portion and a trailing end portion and the leading end portion is either the same size or a smaller dimension than the trailing end portion.

  • Publication number: 20110061279
    Abstract: A muzzle loading blackpowder firearm is disclosed having a barrel with a standard caliber bore therein. The firearm is adapted to fire a projectile having a skirted aft end of a larger initial diameter than the standard caliber bore of the firearm. The barrel has an enlarged bore at its outer end sized to receive the projectile aft end first, and a tapered transition between the enlarged bore and the standard caliber bore so that upon forcing the projectile through the enlarged bore and through the tapered transition, the tapered transition reduces the skirted aft end to the diameter of the standard bore.
