Butchs Bore shine from Acadamy2guns wrote:Conax, I’ve got a 7 mm mag that shot pretty much nothing but Barnes copper bullets. I used every cleaner I had on hand with no luck. I got some Butchs Bore shine from Acadamy and ran a few saturated patches through the rifle and let it sit overnight. Ran about 3 clean patches through the next morning and it was spotless. I was at a gunsmith friend of mine and he ran a Bore Camera through it and said no copper at all. Montana Extreme wouldn’t touch it.
Thank you very much, i will try that stuff!
