Around here lead is considered hazardous material, and shouldn't go into either of the bins. We're supposed to collect it and either drop it off at the hazmat center (free), scrap yard (earn a little money, but there is a line/queue), or have it picked up (also free, but the neighbors will "recycle" them long before the truck picks them up). Casting still appears unregulated, and lead sinkers are still legal in California, for now.
But what would happen at the recycling place with a bunch of pellets rolling around everywhere? If I don't want shot pellets strewn around my yard or house, why not just collect them? Each bucket of collected pellets is a memento of my shooting hobby history, an opportunity to weigh my progress and experience, and wonder, after all that how do I still miss?
