Man ... those cases look awesome. I may have to throw my vibratory cleaner away and start using SS. vibratory is fine for small batches. Yesterday I just wanted to remove sizing lube from 50 rifle cases, so I tossed them in corn media for 15 minutes.
Wet tumbling has significant advantages for filthy range pickup brass, especially bulk pistol/556 brass thas been rolling around in dirt and mud etc. During covid I sold several 10k pistol brass I had been saving up, but first I had to clean it. My RCBS vibratory wasn't cutting it and literally burnt out. I bought the big 5L Frankford wet tumbler and breezed thru all the brass making it brighter than new, and easily paid myself back with the profits. I go through a lot of 9mm and 556, now that I have the wet tumbler, I prefer to use it!
