RE: Cleaning with tumbler
I use the spray on case lube now and there really isn't much of anything left to clean after sizing and loading. My favorite trick after loading some ammo is just to slip an old sock on my hand and sort or feel/rub/inspect each round as I drop it into the cartridge box. Takes about 2 seconds per round and I figure I get them clean and feel for high primers or anything else that might have gone wrong in the works.
