Wow! This thing kicked butt!. I dumped 100 30-06 dirty fired bottle neck rifle cases into it at 180 deg C with some sonic case cleaner for an hour. They came out looking brand new on the outside, inside and primer pocket! My current Hornady sonic case cleaner can't come close to touching (6L, 180w, 200w model) this sonic cleaner. Super; and that's coming from a guy that is very picky.
