There are no operating primary lead smelters in the United States.
Think about that.
That’s the US regulatory environment at work.
All American problems are self inflicted.
I read somewhere that the lead used in the old Monotype hot metal printing machines makes good lad for casting bullets.
Most of those machines are long gone...replaced by electronics.
I recall looking for a house in the SF bay area one Saturday morning a while back....and a guy had one in his garage.
