Abstract
An ignition assembly for a muzzle loading firearm. The ignition assembly includes a conventional breech plug and a modified percussion nipple having a rearward end for receiving a percussion cap and a forward end which extends into the nipple bore of the breech plug. The forward end of the nipple has a reduced diameter so that there is an annular space between the outer surface at the forward end of nipple and the inner surface which defines the nipple bore of the breech plug. The nipple has a rearward fire channel which extends forwardly from its rearward opening and a forward fire channel which extends from the forward end of the rearward fire channel to its forward opening at the powder well of the breech plug. A pair of side fire channels extend from the rearward fire channel to the annular space between the forward end of the nipple and an annular inner wall which defines the nipple bore of the breech plug to enable this annular space to function as an axillary fire channel leading to the powder well.
