I went out with a bench rest buddy a bit ago.45 shots that morning. Soon as we got back he saturated patch and barrel, then let it soak a bit, barrel tilt down. Then came back to it and hit it with a nylon brush,may have to double check that. He has record breaking kreiger barrels. After lunch he said he would patch it out, this was a new barrel with about 250 down it.Said he cleans about at 50.
