CZ, the method I explained is what I do after like you said, 250-350 rounds. For normal range session cleanings, 50-75 rounds, I use a lot shorter method like push thru wet, let set a few hours, and dry patch it. I've never had or used the foam, maybe I'll try it. I do know you can't get the bad stuff until you get rid of any carbon build up. Thanks for suggesting the foam.
