Cleaned a lot of brass inm my day and thought I had it down pat I am very conscience of the condition of my brass. Well I order some additional cleaner for my Lyman Sonic cleaner the other day and when it came, it was the gun cleaning version from Hornady. So, not wanting to send it back I thought I would try it as it was time to cycled the cleaner. WELL, the brass came out looking BETTER than new. I always add a couple other thing to the cleaner and the only other difference was the hornady stuff. Really made a noticeable difference. Guess you never know what will or might work.
