Put about 5 pounds of the oxidized shot in you vibrator with several ~3/8" steel hex nuts. Vibrate for a few minutes, then use a shop vac to remove the dust. Add a pinch of graphite and vibrate a couple minutes. Mix 50/50 with shiny shot. Is lead dust bad for you? Yes, use one of your covid masks and then throw away.
