Okay...What the he** am I doing wrong? I cleaned my Pennsylvania rifle with tepid water and Dawn soap as suggested(after a reange trip last weekend). I did not as of yet have any Barricade as was suggested here, but I did have WD40 (which was also suggested).After I ran dry patches through (which came out clean)I applied a liberal amount of WD40 to a patch and ran it down the barrel. That was a week ago. Fast forward to tonight. I just received my Barracade and a drop in bore light via US mail. I take my rifle down and run a Barricade covered patch down the bore and it came out slightly brown "what the ****". I drop in the bore light and "holy manure" it would appear there is some minor pitting in the bore? I just do not get it? I cleaned with water and soap and dryed then applied WD40. Should the patch come out brown a week later? What am I not doing right? Please help with advise. Thanks.
