Those that point to impacts to recreational shooting and related federal funding streams are right to be concerned about indirect impacts to wildlife management.
But directly as a hunter, the absence of lead wouldn't matter much to me. I shoot monos and love them for my needs. Same goes for bismuth for winged critters. I kill a fair amount of big game, upland birds, and waterfowl every year, and just can't see the price differential on non-toxic ammo adding up in comparison to all the other stuff we buy. (Like someone else said in this thread, stack it deep when you find it cheap.)
Granted, two little kids eat the things I shoot, and I'm not interested in feeding them lead. Lord knows how much 7 1/2 shot I ate as a kid from quail and dove downed with a Winchester 37. Surely that's the source of the stupidity my spouse complains about.
