I decap, then tumble in a Lyman wet tumbler with pins, warm water, dawn, and a pinch of Lemishine for 3 hours( max setting on the timer). If the casings are really cruddy, I’ll run them for an hour with just warm water, dawn, and no pins; then the usual 3 hours with pins. I put the casings on a big beach towel in the sun to dry.
