Wow, I just learned something:
Lead in the bloodstream is a known toxin. And it’s more toxic for the predator, or person, who eats an animal with lead in its flesh than it is for an animal shot with it, said Heiko Langner, a University of Montana chemist and hunter who is working with Domenech in his eagle studies.
Next time I'm shooting at rabbits, I'm gonna tell them "This is gonna hurt me more than it hurts you"!

I'm not worried about a lead hunting ban, though. The way I shoot, all my ammo is labeled "non-toxic"
