Been using Wipe Out since it first came out. Only complaint it does not remove all the carbon. A friend brought over his bore scope and we took a look through the bore scope after using wipe out. No copper but still minor carbon build up in the throat. He use his secret forumala and after about 15 minutes only a trace of carbon. He says you need to leave a small trace of carbon for the imprefections in the barrel. Barrel was a Brux 6.5x284. As far as his secret formula, he going to market it sometime in the furture I think.
