I've been using a Frankford Arsenal tumbler with hot water, Dawn dish detergent & Lemi-shine for several years now and I'm satisfied with the results. Ditched the SS pins a while back since they were a PITA to get out of bottleneck cases and when lodged crossways in primer pockets were a real pain to remove. I recently purchased some SS grit which is small enough so as to not lodge in primer pockets but haven't had a chance to try it yet. At $30/5# it's on the pricey side, not sure the added shine is worth it.
