Discouraged

[Jack]

When I first got my ML, I had to do some experimentation to get it to fire consistently.
I switched the standard nipple to a Hot Shot nipple, and also use the #11 magnum cap from CCI.
I agree with the other advice about removing all oil based substances from the rifle, and popping a few caps before loading.
However, the real secret to reliability with my rifle was simple: pour the pwder charge down the bore with the rifle elevated, then tap the breech area on the opposite side from the lock with the heel of my hand- that seems to shake a few granules of powder into the drum.
If I do that, it fires first time, every time, rain or shine.
BTW, I shoot Pyrodex out of my caplock, which people tell me is hard to ignite ( I didn't know any better), and it still works every time.
