when I need to get copper out I use a mix of 100% janitorial strength ammonia mixed 50/50 with hoppes #9 it's my own formula of butches bore shine ect. ect. and it works. when done I swab the bore with rem. oil the dray patch then another light coat of rem. oil. I have been using this for years with no problem at all only copper free bores,,,,,,,,,,,,,,,

I have never harvested a animal but I have killed quite a few,,,,,,,,,,,,,,
