I just started a batch in the stainless tumbler. I'll check it at 45 min. I used 1# of brass 40 S&W, 1# of stainless media, 1/2 of .5 case of Limishine and a 1/2 teaspoon of Dawn dish detergent. In each container. I can probably run more but one site suggested using 3# total weight for each container, including container. That should be about 100 cases.
I'll keep y'all informed.
