Used ultrasonic but I'm not patient enough to wait for them to dry same with SS media. I throw'em in corn cob with some polish and finish them off on a brass prep station. The SS even get the primer pockets shiny but I found it cleans to good or might shorten the life of the brass because its to aggressive, not saying its true but just what I think, been wrong before.
That's where annealing comes in. I anneal after two firings. Then the only thing that will wear out will be the primer pockets. I don't think there's any prevention for that, though. Unless someone wants to back way down on powder charge. I'm not gonna do that silly business.
