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.
