Decided to wash my 45ACP brasses--about 300 pieces. Dumped all into a bucket along with some Arm&Hammer laundry detergent and lots of hot water. Put on a pair of gloves. Stick my hand into bucket. Stirred and shake and toss for about 10 minutes. I was going to swipe each piece with cloth, but didn't because they were already quite clean. Rinse. Put each brass open side down on old plywood to dry. Next day, reloaded a few rounds. Work just fine in Dillon. Actually feels cleaner than ones from the tumbler. No toxic dust. No expensive media and tumbler. A bit more time. Brass not polished pretty though.
