Abstract: An action breech assembly features a one-piece action housing movable between a horizontal at rest position and a vertical cocked position to move a cocking plunger rearwardly as a result of a lateral offset between a pivot pin on which the housing is mounted and a plunger stop pin to which the plunger is attached. Pressure relief devices are provided for the powder chamber. An adjustable sizing die permits the amount of material removed from an external portion of a bullet to be adjusted to optimize the performance of the bullet in a particular rifle barrel.

Abstract: A firing mechanism having an action housing whose rotation simultaneously cocks the weapon and engages the safety. The rotation also provides access to a nipple that supports a percussion cap ignitor that is positioned underneath the weapon so that the exhaust gases are propelled downwardly and the ignitor cap is protected from the weather. The trigger pull force and distance can be individually adjusted to the preferences of the firer.
