Has any one tried this stuff? I have been using butches bore shine and really liked it. I cleaned my 338 edge last night to were i was happy with it when My neighbor came by and told me to try this stuff he bet my barrel was not clean. I told him that there was no copper coming out of it after i cleaned it. But i went on and tried it i ran one soaked swab throw the barrel and let it set about 8-10 min. I then ran a good tight WHITE patch throw it and it came out looking like it was a piece of blue jean!!!!!!! I could not believe what i saw!!! BBS had left a lot of copper in there. so i had to check this stuff out on the net and this is what i found on there sight.
