Krell1- For disposal I would look to a metal recycler, otherwise you are talking hazardous waste! One of the reasons to use steel or a substitute. Since the lead shot is 100% lead and the action levels are in the parts/billion range, you can see that even a v small amount of dust generated from pouring/handling can contaminate a large area, and one pellet ingested by a child or animal can cause acute poisoning.
