I use a Harbor Freight rock tumbler. Dual drum. For 9mm and I wash for 30 minutes, rinse, then size and deprime while they're still wet. Tumble again for an hour and sometimes more, roll them on towel then lay them on a screen and dry overnight.
For .223 and 6.5 Grendel I size and deprime first, then one 30 minute wash, and a second one hour wash. I can fit at least 250 cases at a time.
I use a few drops of dishwashing liquid and a tablespoon of lemon juice per drum. I've never had to clean a primer pocket.
