I understand what you are saying about JB compound, but, for example, I have a rifle in .375x338 Mag that copper fouls so badly that even JB bore paste doesn't do it. Even the stronger solvents don't seem to phase the stuff.
I have several other rifles that are just as bad.
What would you suggest I do? Please don't say buy another rifle. If I do, my wife will kill me.
