How about Hoppes No.9 copper gun bore cleaner? Anybody use and like that stuff? I have some and have used it, seems to work alright but I don't have nothing to compare it to and I don't bore scope my bore but if I see a bright shiny mirror bore I'm happy.
Hoppes #9 will remove copper from bores it just takes patience and letting it sit for a couple hours or more between brushing/patching. The stronger solvents are faster.
As far as general cleaning prior to lubricating, #9 is almost perfect IMO.
