So I just dug up my 1911 Enfield 303 and shined a bore light up the barrel only to see tons of gunk. I ran bore brushes and patches through it and they came out completely black and then brown. I cannot tell if the barrel is pitted because of corrosive ammo or just years of build up. Any ideas or products of what is best to clean it out?? I know the wood is rough but I don't wanna damage it anymore then it is.
