  • Patent number: 5623779
    Abstract: A muzzle-loading firearm designed to utilize an ignition device carrier and to discharge projectiles having pre-cut rifling. The ignition device carrier serves to facilitate easy installation and removal of the primer or percussion cap required to discharge the firearm in addition to protecting both the primer from inclement weather and the shooter from powder detonation. The carrier also provides a means for positive mechanical extraction of the ignition device from the weapon. Projectiles for the firearm have the rifling grooves cut into them by forcing the bullets through an engraving die fashioned from a portion of the rifle barrel or from a separate barrel of slightly different dimensions than the barrel of the weapon which will fire the projectiles.
