I've been working on the .358 barrel that I so foolishly shot some jacketed in, and found I was about out of Sweet's. Went to the gun shop yesterday to pick up some more and was told that they were out and it was on order. He told me that he had been using a new product and had found it was every bit as good as Sweet's and personally he prefered it to Sweet's. Yeah, sure! Only because it was in stock, right? Well, I bought a bottle called "Pro-Shot Copper Solvent IV", gave it a test ride today, and was duely impressed! It removed the copper quite eaisly and smells like 409 cleaner, no ammonia smell at all, which should make it eaiser to work with indoors. Also, it isn't supposed to be harmful to barrels, unlike strong ammonia cleaners, which is one reason the gunny said he prefered it to Sweet's, as when a customer walked in while he was in the process of cleaning a barrel. You may find it to work well for you too.
The barrel is clean and will not be desecrated again with jacket fouling. EVER!-JDL
