Not wanting to expose your kids to lead is hardly ridiculous.
Completely agree with that, but I just don't think that is an issue, but I respect your concern. It's the second part of your statement that I take issue with.
I didn't think it was an issue either until I saw an x-ray of a carcass killed with lead and copper bullet. Lead fragments had spread way beyond the wound entry area to the tune of 10 or more inches.
