Turpentine is a very old remedy claimed to be good for muzzle loader leading. I doubt it would harm anything. I also would not hesitate to use a stainless bore brush in there. Once you get it clean I think it won't recur unless you use soft lead bullets at high velocity.
I also remember reading in The Rifleman about cleaning a really badly lead-fouled .22 rifle by heating it pretty hot over a stove burner???
