OK. I am pretty old fashioned with my reloading and processing of brass. I use a Frankford Arsenal vibratory tumbler. I use walnut media generally, sometimes with rouge for polish. By the way, it gets inside the cases, which I have found to be no problem at all when firing. I highly recommend rouge treated walnut media if walnut is what you use. I am looking to make my life a little easier if possible. Stainless steel media is my most realistic option. Do you simply rinse the media or shake the carbon and debris off dry after each use? Is there a down side to stainless? Since the tumbler is already bought and paid for, does it make any sense to switch to an ultrasonic or liquid machine? In the end, I can use walnut for the rest of my life. It has worked for the first 50,000 cases or so. I just want your valued input and opinion on why I should/shouldn't switch and if I should, which way I should go. Thank you, Kip.
