I don't really care about the lead being ingested by people, even kids. I think if you use a good controlled expansion bullet, the impacts are minimal at best. At my age, I really don't really give a shit about tiny amounts of lead. I butcher all my own game and my philosophy of "when in doubt, throw it out" limits lead exposure to about zero. I also try to stay off shoulders and other large bones, shoot controlled expansion bullets, and carefully watch my shot placement, both because it makes a mess, and secondly because of the lead. I also try to make sure all my bullets exit, or at the very least, make it to the off-side so I can recover them.
But, the impacts to birds, I do care about that and honestly if I make the switch to all copper it will for the potential impacts to wildlife.
I do have concerns about all copper bullets and their performance, in particular in rifles shooting less than 3k FPS in regard to how they kill game. I also hate having to work up new loads for every rifle I own.
If this is something that is going to be legislated, I hope the bullet manufacturers continue to work on improving the all copper bullets. I also hope they work with rifle manufacturers to extend magazine length and throat geometry to something better suited for all copper.
My 2 cents.
