I wet tumbled in the late '60s in a machine shop where I worked. The "wobbler" (today called "vibrators") held about 100 gallons of liquid. Maybe 20 gallons of ceramic media and one or two 20 gallon drums of machined parts, depending on the size of the parts. When working, the whole shop shook.

I tried wet tumbling cases a couple times but the pristine brass didn't shoot any better, and the mess wasn't worth it (I could easily get shiny brass by just leaving the tumbler running a bit longer (corn cob blast media 14-20). I shoot alone, no need to impress anyone with my "purdy" handloads and I prefer to judge my handloads by what happens on the target...

Way back when, brown handloads were a sign of a handloader, a "badge of honor"...
