It might be over-sensationalized, but can we say it's all BS without offering our own conclusive counter-science/proof?

While I do use lead bullets, I'm also mindful of how I handle lead components. When cutting up game, I will waste a little meat rather than carelessly tossing it all in the grinder. That's me, but I've been in the medical arena enough to see what heavy metal toxicity can do to a person. The actual risk when something is ingested is a variable affected by age as well as by where/how/how much is in the body.
Of course, we can bring up all kinds of other factors that cause death to animals, and while those might be legitimate issues, to pretend this is a non-issue because something else might be a higher-risk issue is a bit of distraction and denialism.
