Not so much one setup for tumbling but if you over speed the tumbler motor or gear ratio you get more of a wave action inside the drum. then yes. overspeed and steel ball bearings would clean them in a larger sized tumbler no problem (need the drop distance in the drum to be about 6-8 inches). Although there would be some dust you wouldn't want to breathe left over and running a tumbler dry with metal inside is not only noisy but quite destructive to your barrel.
wouldn't recommend a wet tumble here
