The OP was about personal choices for hunting, not about legislation.
Do you dispute the arguments about the toxicity of ingested lead? There is a lot of bad information floating around, but there is also good science.

One could argue that hunters voluntarily choosing non-lead projectiles would decrease the incentive for legislation.
I have no qualms about sending cases of lead projectiles downrange at a properly designed and maintained facility. I shoot clay sports with lead. But I fish with lead-free tackle, and if I hunt this year I’ll probably try a lead-free option.
