I use something very similar on every used gun I buy when I first bring it home, which is every gun I own since I don't buy new ones..
I want to get the barrels as clean as I can, and get rid of any copper fouling, then switch over to lead. It seems to do a great job, and I've only had to do it once on each gun.
