Oh crap...I've tainted the beloved pink slime thread with lead!
And, though lead shot and hunting using shotguns interests me little, a quick google search revealed a tidbit of human ingenuity by way of past practices in the manufacture of lead shot.

Simple, intuitive, and pretty cool.
Sorry for furthering the pink slime hijacking agenda.
