This statement is absolutely false, and just goes to prove that Grouse Guy Ben(the deer poacher) Deeble doesn't even read the anti-lead crap he dumps here.
But this is nothing new, because Ben has demonstrated in the past that he is too stupid and too agenda driven to digest the material he dumps here anyway.
This paper is not about species that are immune to lead poisoning. The subject is lead poisoning in humans. The only non-human species within this paper are where it attempts to compare lead toxicity in humans to the physiology of mice and rats.
Nice to have some unethical slob hunter who gets arrested for trespassing and shooting game out of season lecturing us about what ammo to use based upon links to papers he obviously has not even read.
