One more thing -

I've been told that if there is that much fouling at the muzzle, it's probably worse close to the throat. i don't know if that's so or not. I would assume that close to the muzzle is where the bullet is reaching it's top velocity, and copper wiping would be worse. But there's also less heat at the muzzle. Someone with more knowlege that me will set us strait.

My point is, when it's gone from the muzzle, there may be more still in there. Kepp pushin' those patches until you feel good about it.
