Rol Page: the ultrasonic cleaners take a lot more attention than the tumblers require, although some guys absolutely swear by them they still have to use a tumber or try to move Moma's casserole out of the oven to get the cases dry. I would not suggest that if you want dinner that night (lol).....
I have a Dillon tumbler that I really appreciate. I fill it, turn it on and go do something else for about half a hour to 45 minutes or so and the brass comes out nice and clean and shiny. I use a mix of corn cob and walnut media to clean the brass and still use some of the Dillon blue case cleaner if I haven't changed out the media in a couple of years - and yes, I clean and reload a bunch of brass but the media lasts a long time.
I usually de-prime my cases after the first tumbling and then depending on how much dirt/crud I see in the primer pocket I may tumble again before reloading. The last time I tumbled brass I tossed in 300 380 acps and 100 30-06s and 45 minutes later they all looked almost new. I think I need to clean up a bunch of 357s next.
