if your gonna use a brush, use nylon brushes. I can't see putting metal brushes down my barrel. IN fact, i have stopped using them all together. I usually dunk a patch in the cleaning solution and then squeeze it so it's not dripping wet. Run it down the barrel and then out. Wait 5 minutes and use dry patches to clean it. I do this twice and i am good.

Then i run a lighty oiled patch down the barrel and then a dry patch after that. Done!.
