A couple things I have come to learn about wet tumbling. It can be a huge pita with the large tumbler and smaller batches. I much prefer my cheap dual drum Harbor freight unit for all but the biggest of batches. Don’t expect that nice chamfered mouth to survive a wet tumble that completely cleans the brass. Unless brass needs trimmed and chamfered anyway, I limit the time in the wet tumbler to a out 30-40 minutes, otherwise those nice chamfered case mouths get all peened over.
