If anyone still shoots a Black Diamond here is the issue. I've had this for 12 years and I just took it out of the box. I started reading and it seems to be very dirty with the Flamethrower system. Some go to a single port #11 cap and has half the blow back and stays much cleaner.

What I can't find is what size nipple do I need? I found one but its a lot shorter than the Flamethrower. Not sure if that will cause harm. I just need something to go on because I'm totally green to the muzzle loader world.
