Abstract
A nipple for a muzzle-loading firearm includes a generally cylindrical main body with a forward end of smaller diameter projecting forwardly and a rearward end of smaller diameter projecting rearwardly from the main body. An ignition bore extends completely through the nipple along the longitudinal axis thereof. The rearward end includes a tapered exterior surface with a forward tapered portion and a rearward tapered portion having different slopes. An annular groove is formed in the forward tapered portion slightly forward of the rearward tapered portion, and the rearward tapered portion preferably has a steeper slope than the forward tapered portion. Each tapered surface of the rearward end tapers to a smaller diameter from the main body rearwardly. A percussion cap is mounted on the rearward end of the nipple with the forward end of a cylindrical side wall in continuous contact along the rearward end of the forward tapered portion, aligned with the groove, to form an annular space between the rearward tapered portion and the cylindrical side wall of the percussion cap.
