OK seeking some real insight into this, both cause and effect, without a borescope I'm thinking they can't be spotted very well? What contributes to them? Powder-overbore-or other factors I'm not thinking of?, I'm figuring that rather than the blue/green of jacketing and copper it must be more of a black or dark grey on patches. Just did my major barrel cleaning and match barrels clean to the point of only solvent color on final patches but the two factory barrels seem to still produce that dark discoloration on patches that never cleans up completely. Use barnes cr10 and normal bore solvent's as the final, never use metal bristle brushes but stiff nylon instead. No trouble chambering or with accuracy but some barrels have a few rounds down the tube. Educate me on this subject please and what do's or don't's to employ, I may have no trace of them and my two factory barrels deliver match barrel accuracy but seem to be copper mines compared to lapped match barrels.
