I get to clean up the grandsons' range room at school twice per year. Mid term is just to get all the mess off the floor and out of the target boxes before Christmas break. Summer break is a total clean up of the room. This years mid term clean out yielded 21 3/4 lbs of 96% pure lead ingots. I melt the pellets in a cast iron pot over the fire pit. Yea, it takes a lot of hot burning wood to melt a heaping pot in a few hours, but I have lots of scrap wood.
