Just a thought.
If lead was even a fraction as dangerous as the government leads us to believe there would be no one alive my age (74). We would have all died out at a young age from lead poisoning, Mercury poisoning. etc.
We grew up surrounded by lead. Our toys were made of lead and painted with lead paint. Everything was painted with lead paint. Baby cribs and play things were painted with lead paint, but of course young children would never chew on their things.
There's hardly a boy that didn't coat coins, using their fingers, with Mercury they got from the school science lab. Now you break a mercury thermometer they call a hazmet team.
Whole towns were built on lead dirt from mines. The children played in lead dirt, breathing the dust, their whole young lives.
Very early water pipes were lead. Ever hear the saying, "He got hit with a lead pipe". Later copper pipes were joined with lead.
Even the auto gas contained lead.
Many shooters my age have been casting lead bullets and shooting lead bullets in poorly ventilated indoor ranges for over 50 years. No way would we still be alive if lead was even a fraction as dangerous as the government wants us to believe.
One thing to keep in mind.
Whenever a government agency is created, those people's primary job is to to make everyone think they are actually doing something useful and protecting us common people. The ATF and EPA are good examples.
So believe what you want but us old folks are living proof that the lead scare is wildly over rated.
But sure, protect your kids in every way possible.
