So , I was talking to a S&W tech today and He sez NEVER (and I repeat ) NEVER use a stainless brush on your bore !!!!!!!!!!!!!!!!!! So because I do that on occasion I thought I should get you guys to give me your opinion on cleaning . I start with patches and Hoppe's #9 then go to patches with Barnes CR-10 and if I still have an issue I brush with CR-10 and a stainless tornado brush . I finish with #9 and dry patches . The tech (who I thought sounded like He knew what He was talking about ) Said "200 strokes with a stainless brush will damage your barrel !!!" Let me reiterate that my techniques for cleaning are vastly different for lead and copper and I would like to hear about some other fluids , gels , brushes , patches , blah , blah , blah . I could be stuck in a rut . THANKS !!!
