What media do you use to tumble rocks?

Most depriming dies are also size dies and as such if you are running dirty brass through them can scratch up the interior surface of the die. I always tumble first and then deprime/size. Brass cleaning is the same either way and you don’t have to worry about checking the flash holes for stuck media.
