I am cleaning a new pistol barrel with the 200 rounds I put through it last weekend. I simply cannot get a clean patch after brushing. I've used hoppes 9, slipp Carbon killer, and Kroil. I've put on new brushes thinking it was the brush itsel. So I brush, clean with hoppes, then let it sit 20 min. I run a few patches through until they come out clean, then brush again, and the next patch come out very dark, not just light traces. Any ideas how to get this thing clean once and for all?
