I have 2 tumblers
#1 Arsenal Quick-N-EZ 110V Vibratory Case Tumbler is a dry tumbler, I use it first to do a quick clean, I don’t like to run dirty brass thru the press.
#2 is a Harbor Freight Chicago Electric Dual Drum Rotary Rock Tumbler

Here are a couple of pics..

This is after 1 hour in the Vibratory Case Tumbler. It’s very “clean“.

Here is a picture after the wet tumbler.

This is very polished.
