rifle cleaning?

Since my last post on this thread I've had a chance to use Montana Extreme 50 BMG copper solvent. I'd have to say it's my new favorite copper solvent. It's very strong and does a wonderful job, but let me offer a couple of tips. First, like I said it's very strong stuff. Use it in a well ventilated area and whatever you do, don't put your nose over an opened bottle and inhale. BTDT. Second, it's strong enough that using it with brass jags (or even nylon brushes with a brass or bronze wire core) can give you false copper readings (blue color on your patches). I have found that applying it with a loose fitting wool bore mop with a steel core (you can get them at Walmart) is perhaps the best way to go. Then, after letting it sit for 10 minutes or so, push a patch through the bore with the bore mop. That way if you see blue on the patch you'll know it came from copper in the bore and not your brass jag.
