not really, lead poisoning is from soluble or gaseous sources, lead is basically inert,
I had shot making gear till 3 years ago, I used to make 60 to 80kg a day,simple enough to do , did it for 10 years, and also bullets and slugs,,before that,so at least the last 20+ years ! and reload of course,, and supply my mates that reloaded. lead becomes dangerous if it fumes, about 1500*C , but the melting point is about 330*C
