It's Applesmasher's confession time:
I don't wash cases.
I don't tumble them, I don't vibrate them, I don't anything them.
If they're caked in crud because they were shoved into mud, I let them dry, and then I use a little high pressure air to blast the crud out. That's all.
If they're whole and generally healthy, I then size them and carry on.
Your general approach of scrubbing them seems to me to be overkill. I'd wipe the exterior on a towel perhaps, blast out the interior with canned air, put them in a ziplock bag and go to do something else with my time. Your biggest risk would be leaving water in them. My method doesn't risk that.
But hey, at least if they're shiny it's easier to spot any problems. So I wouldn't call it a complete WOMBAT (Waste Of Money, Brains And Time).
