[QUOTE="VinceMule, post: 2550351, member: 122164"] Proper cleaning never hurts barrels...proper. My bore scope is right beside my cleaning station. First, good brushes do the cleaning, first 60 strokes does the most work and they are completely worn out at 100 strokes. Pro Shot Broze Bristle brushes and Dewey brushes are some of the best, there are a lot of junk brushes out there. We have struggled with the carbon issue for a while. Got together with some of the top gunsmiths on Accurate Shooter that chamber rifles for F Class shooters where they shoot 10 shot strings fast...they have to learn to deal with the carbon or had better stay home. Couple of things that I learned from these gunsmiths: A. CLR left in the bore no more than 5 minutes, brushed well, will get out most if not all the carbon. You absolutely must neutralize that CLR and a number of fluids will do the job. B. When the brushes have 60 to 100 strokes on them, I save them for winding Fine Bronze wool in the bristles. This will not scratch the finest of barrels, and I shoot a lot of Krieger, Brux, Lilja, Hart, and X Caliber barrels, no Bartline barrels for me. The calibers I shoot are from 223 AI to big 7mm. C. some powders are much worse than others, check a heat index chart. 8208 is horrible to get out in my 308 Kriegers, but brother does it hammer the bullets in a bullet hole. R#15, and H4895 are almost as bad. I pulled my hair out trying to get the carbon out of the barrel until I was told about the Fine Bronze wool( inexpensive on Ebay). D. Penetrating oil called Free All is an amazing penetrating oil, and I have tried many others. Free All has a chemical in it that actually dissolves carbon. Soaking with Free All will break loose a lot of carbon, and if you can do this at the range while the barrel is still warm, the cleaning is much easier. Free All is available in a spray can and a 14 oz trigger pump can. E. With a issio or Montana extreme plastic brush, you can wind the Fine Bronze wool in the bristles, and can scrub back and forth in the problem areas. The Hawkeye bore scope magnifies 25X and will show scratches in the bore. Rest assured that in your finest barrels, the fine bronze wool will not scratch the barrel. A couple of notes from the gunsmiths, if you don't get the carbon out, it will never come out due to the fact that heat and pressure will make the carbon so hard that it will not even be able to be cut out with the exception of Silicone carbide, 600 and 800 Grit available from BRownells. As guys on this and other sites state how they clean their rifles, they rarely set the stage as to whether it is a 222 Remington or a 7 Rem Mag.
