Have I got to start looking for lead ingots again? Or should I just go through the parking lot with a screw driver picking lead off of wheels?
Knowledge and powder and primers. You will never be out of ammo.
Wheel weights haven’t been made of lead for years, you’ll have to find old cars.
Get a vintage car. While doing body work on a 1968 rear fender, I put a torch on a body seam and flowed several pounds of lead into a bucket, just from one seam. Back in the 1960s I toured an auto factory and watched workers slabbing hot lead on body panel joints. Old cars are full of it. They no longer use lead. When doing body work on that same car I used a lead substitute.
