I checked out an estate sale in my neighborhood today that advertised tools, on the off chance I might find something useful like gardening pots. There were about five other guys in the garage grousing about how everything had been picked over and it was all junk. It was dark inside too, but thankfully I had my flashlight and starting poking around some of the little nooks and crannies. Stumbled across something that looked like a huge wheelweight, then two more, then another big weight that looked like maybe a harder alloy. All were pretty soft against my dull knife. Total for 27 pounds plus a little drink coaster from Germany was $8. Definitely wasn't expecting to see lead of any sort in this area. I have no idea what hardness or alloy it is, so I figure I'll melt it down, cast a few bullets for hardness testing and turn the rest into ingots in the meantime.
