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.

[ What is claimed is:] [1.] An ignition assembly for a muzzle loading firearm having a breech containing a powder chamber, said ignition assembly comprising:(a) a breech plug for mounting to said breech, said breech plug having a forward end containing a powder well and a rearward end containing a nipple bore which is defined by an inner surface, said breech plug having a forward opening to said powder chamber at said forward end for enabling said powder well to be contiguous with said powder chamber when said beech plug is mounted to said breech and a rearward opening to said nipple bore at said rearward end, said nipple bore extending from said rearward opening to said powder well; and(b) a nipple having a rearward end for receiving a percussion cap and a forward end connected to said breech plug and extending into said nipple bore, said nipple having a rearward fire channel, a forward fire channel at the forward end of said nipple extending from said rearward fire channel to said powder well for conducting a first stream of burning gas from a percussion cap at said nipple to the powder in said powder well, a rearward opening at the rearward end of said nipple to said rearward fire channel for receiving an explosive discharge from a percussion cap, at least one side fire channel spaced rearwardly from said powder well and extending laterally from said rearward fire channel to said nipple bore, a portion of the forward end of said nipple within said nipple bore being spaced from the inner surface of said breech plug to define with said inner surface an auxiliary fire channel extending longitudinally from said side fire channel to said powder well for conducting a stream of burning gas from a percussion cap at the nipple to the powder in said powder well, said forward fire channel being substantially smaller in cross-sectional area than said rearward fire channel.
