Alarmist talk! That they don't SMELT lead form ore in the USA is all this says. I doubt that we smelt copper from ore in the UK and we certainly don't mine diamonds in the UK either. But I've no problem buying either.
Simply put, as discussed on USA Forums most bullet lead alloy in the USA is made from re-claimed lead, that which is sold to scrap metal merchants, or is imported. I doubt that here in UK we've smelted lead for a long time either. Or made buggy whips.
