Water likes to stay in the primer cup and the flash hole. I usually don't use wet-cleaned brass for at least a week after tumbling it and then it stays spread out on a wire rack to dry. My preference is a two-week drying time in a good environment to be sure.
Yeah, I either spread the brass on a towel and let set for a few days, or bake in my salvation army powder-coating toaster oven. I guess this one just made it past my check.
