I tumble in container and just pour 1/4" chicken wire tray I built from hardware cloth (wire). Some of the .223 fall through, but 9mm dont. The first couple of bakes coated the wire in PC and they stopped having small marks on outside of bullets. Some guys get the mesh baskets from Bed Bath and beyond or dollar store, I couldn't find them. Plus I am building a chicken coop, so can use the rest of roll.
