Wynne, I am using SS media in a Tumlers Tumbler wet. This gets your brass as clean as new and it looks like new as well. I am not sure this is a good thing however. After talking to a few point blank benchrest shooters who almost never clean the brass that removing that fine film of fouling from the neck decrease’s there accuracy. Not sure how I feel about it just yet but I am trying there way for awhile. I do use OOOO steel wool on the outside of the necks down to the shoulder, and I do clean all of my primer holes before I seat a new primer. One thing I do know for certain clean shiney brass looks good but it doesn’t win any matches by it self.
