Hey everyone, I shoot anywhere between 110 and 150 rounds through one of my 1911s every weekend and the throat area always takes forever to clean even after letting it marinate in Hoppe's 9 for a few hours. The barrel has had close to 3000 rounds through it. Having run a bronze brush through the barrel (in one direction only, never pulled the bore brush back the other way) so many times, it looks like I have scratches all over the place along the rifling. The rifling itself looks smooth. Yesterday I got a little tired of running the brush through the entire barrel just to get the throat clean so I used a small bronze bristle toothbrush and gently went back and forth where I could see lead deposits and it worked really well. Any adverse effects doing that? The bristles are short enough that the brush doesn't "lock up" on the way back. Here's the best picture I could take of my barrel right now, looks alright? Also in terms of accuracy am I right to believe that since the bullet only touches the rifling, all that matters is the smoothness of the rifling?
