I was looking at a used muzzleloader at my local gun shop the other day and asked the owner for a bore light. He has a rather slick idea for checking them. With a normal bore light dropped into the barrel you still can't see the first couple inches near the breech. He has a couple small aluminum plugs in various calibers about 1/2 inch long, polished on the ends. Drop the appropriate size down the bore and shine a light in from the muzzle and it lights up the whole bore rather well.
I never heard of this before and thought it was a rather slick idea. I bought a rifle once that had a bad rust ring near the breech I could not see with a bore light. Apparently it was left loaded for too long in a humid climate. The only way it would shoot worth a darn was with heavy loads or extra wadding to get the ball seated ahead of the rust ring.
