Cleaned some 50 BMG today. First pic is cleaned with walnut media and lubed, sized, deprimed and at this point I would usually re-tumble to remove the lube. Primer pockets and insides pretty dirty still. 20 50BMG cases with SS media, 9mm case of Lemishine and a squirt of Dawn. 4 Hours of tumble equals some dirty water. After I rinse a few times I let some clean water run in the tumbler till all I get is clean water with no soap suds. Dry them off and then place in tray to be "baked" at 135* on convection.
