So I think lead is actually sorta like windmills in some sense. I mean that it is a documented problem in some areas, but in others it likely isn’t. Planting a windmill in a mountain pass is significantly different from siting it in a sea of cropland. As such, applying one size fits all solutions for all locations is not likely to be effective or popular. Non-lead bullets maybe one solution, packing out or burying gut piles may be another. Lead is only documented as an issue for avian scavengers. To my knowledge there is no documentation of lead biomagnification in mammalian scavengers or related to human consumption of game meat. If you can reduce the potential for avian scavengers to use gut piles from animals shot with lead, it’s worth a little time to bury or conceal what you leave behind.
And finally, as someone who has used non-lead rifle ammunition for hunting for a couple of decades, I will tell you that anyone who thinks there are no drawbacks to its use for hunting hasn’t used it or seriously evaluated it’s effectiveness. Every solution you propose to a given problem will have drawbacks. Non-lead ammunition results in smaller wound cavities and more wounded and lost game.
