Abstract
A breech plug and igniter system for a muzzle-loading rifle includes a generally cylindrical breech plug with a cylindrical chamber formed in the rearward end coaxial with the plug, and an ignition bore extending forwardly through the plug from the forward end of the chamber. A percussion capsule has a forward end removably mounted within the chamber and a rearward end projecting rearwardly from the rearward end of the breech plug. The percussion capsule has a metal percussion cup mounted in the rearward end of the capsule with the cup base flush with the base of the capsule. The percussion cup has an open forward end communicating with a bore in the capsule, which communicates with the ignition bore of the breech plug. The rearward end of the capsule has an annular lip projecting radially outwardly around the circumference thereof. A bolt has a slot formed in the side wall thereof spaced slightly rearwardly from the forward end of the bolt for receiving the rearward end of the percussion capsule. An opening in the forward wall of the slot has a width to receive the exterior diameter of the capsule, while the slot has a width to receive the annular lip, such that the bolt will removably receive the capsule rearward end within the slot to insert and remove the capsule from the breech plug chamber.
