Got it used. Looks new, but I've been polishing it with Mother's Mag, and that stuff gets into the crevices. Also, I would think letting the cylidner and barrel soak in it for a while will make removing lead and copper a bit easier. I've never field stripped a Ruger and I figure why not really get it clean? if it doesn't look bad when I get it stripped, I'll probably just use Gun Scrubber on the internals, followed by a lube.
I was going to us it once, but a couple of pretty knowledgable people told me that it can be hard on some finishes. I decided it was cheaper in the long run to use regular gun cleaning products, and not take a chance.
In black powder competition, we used 50: 50 Simple Green and water to clean bore fouling between events.
For final cleaning, we pump Ballistol up and down the barrel and use it to clean exterior parts. After patches come clean and all parts are cleaned with Ballistol, simply patch the barrel and exterior dry. Thats it. No water.
The guns we use this on are either "in the white" with no blueing or blued steel. Stainless steel is not used in or competition, because it wasnt invented in the Civil War. Ballistol keeps these guns rust free. Dont know how it works on centerfire guns.
