I've been using that CVA "Barrel Blaster" in my Ruger #1 and 30-06 bolt rifle. It seems to work pretty good, but I can;t really evaluate it because, after I let it soak and scrub it out, then Butch's Bore SHine and another cleaner follow it. The instructions say you can let it soak for up to 24 hours, but the longest I've allowed it is about an hour or two, before moving on to continue cleaning with other stuff. WHo knows how well it really works. Not me.
I will say though, that stuff does have some pneumatic power to it! It will push a double, over-sized patch right out of the bore (stuck in there so the foam doesn't come out and get into the falling block)! You spray a quick shot into the muzzle and, seconds later, it's expanding and trying to come out both ends.
If you are trying to "get the lead out" give this a try. Mix up 50% vinegar with 50% hydrogen peroxide, plug the barrel and pour in this solution to fill the the barrel completely. Of course have the firearm with the barrel verticle-I like muzzel down. Wait for the solution to do its "magic (10 to 30 minutes usually works fine) then pour out the solution. Wipe barrel with clean patch then brush barrel if needed. Repeat as necessary until satisfied with results. I've been using this method with my handguns that needed leading cleaned out and it works great for me. After finished shooting for the day clean and preserve firearm as usual.
