Well I'm not a fanatic about it snuffy and the only thing that I'd worry about is casting bullets but since I have no experience doing it I'll just be quiet. I never worried about lead in game or the environment. Only the fumes from the story that foundry owner told me. I was only relating a real occurence that happened that might affect guys that cast bullets. Shame on me.
And if I did cast I have a good ventilation system going .... just in case.
(and I don't believe in global warming or solid copper bullets!)
BTW, I used to work for Rockwell International in Oshkosh many years ago and my oldest daughter lives there. I used to drive from Wautoma every day. Now I'm in the Wisconsin crime capital of Racine.
