This is fascinating to me. I love to tinker, and I love to improvise and I love to keep my options open. This presents another option I had wondered about but didn't really know enough, so I thought .
I do have one question though, WRT recovering range scrap that may contain zinc bullets if this becomes more common...
Maybe some people are doing this already and we need to be aware that we may begin to encounter zinc in range scrap?
How would one separate the zinc from the lead? Just keep the pot temperature low enough that any zincs would float and could then be removed and thrown into a separate bucket for melting zinc at a later time?
