I really like how clean my brass comes out wet tumbling. I bought the big drum when I ordered my tumbler and it works excellent. I have enough brass for each caliber that I shoot regularly to shoot all summer and then tumble in the fall for winter reloading. The problem was the calibers that I don't shoot often or only have one or two hundred pieces of brass for. I just acquired 250 .32 H&R Magnum cases and want to clean and load them. I built this small drum out of a 12" piece of 4" ABS and some 1 1/2" PVC for the paddles. So far so good.
