Re: barrel break in advice
I agree with Broz, which is how Darryl Holland said to do it, and how ive done several of my barrels (even before i became a fan of Darryl.) With my .270 Win if i clean it every 100 rounds with a wet patch nothing comes out. I tried waiting til 200 rounds and the patch was actually dirty. But with my AR i can shoot 1 round and have nasty patches coming out. I also do not use steel or copper brushes on my rifles, only nylon when it really needs it. I find that a 50/50 mix of Peroxide and vinegar works great. If it does not get eveything clean i go for good ol hoppies #9. Sometimes in my pistols it gets really rough (i shoot cast bullets), so i use a bore scrubber solvent, and in pistols ONLY metal brushes.
