Thanks guys for your help! I went dwnstrs this morning, had used Kroil last night. I used the bore brush {brand new when I started} w/Kroil on it about 10 times down the bore, did seem to be improving, clean patch, was not as black. I went to my buddies place, said he had some good stuff we'd try. The stuff he had was in a military green can, was military grade bore cleaner, when shaken it looked like heavy milk. About 5 times on bore brush down the barrel, you could feel the fine grit from the brush between your fingers, series of patches and more "milk" back and forth for a total of 3 scrubbings. Last patch thru the bore came out a very light "gray" color, think we hit pay dirt! The riflings in the barrel are sharp, when pushing the Dewey rod down the barrel, the rod twisted every revolution, so the barrel does seem to be quite good. Now, just need to shoot the dude and see how accurate it is. Thanks guys for your ideas and help, as far as the copper Chore Boy, I'd even had fantasies about using 0000 steel wool on a brush...... no need to now!
