Re: Best copper remover yet!!!
I'll second that. I'd cleaned and cleaned until I thought the barrel had to be clean. Used Butch's, JB, Blue Wonder, SC, etc. Might have even used some Sweet's early on in there. Patches finally came clean. Had another barrel in for borescoping, so I took the new Savage along. Not one spec of powder fouling in the whole barrel (yay!), but while the bottoms of the grooves looked shiny like a lapped barrel from the button pulling thru, the tops of the lands were more like a file, perpendicular to the direction of bullet travel, and loaded w/ copper. Crap.
Took it home, gave it several applications of WipeOut, which did get out a fair amount of blue (not as much as I would have thought, considering how much I saw in there), then ran some patches of Sweets thru it, and they came out clean, even when I left them to soak. Figured one way or another, its about as clean as I can get it for now, and besides, it still shoots good. I don't like the copper fouling at all, but if it shoots... so what?
