Essentially, hunters are saying to the government "i want permission to go and hunt." and the State's response is something akin to "fine, you can hunt, but in order to safeguard animal populations, we're going to restrict both the number of animals you can kill, and we're going to limit what types of ammunition and firearms you can use."

I'm not sure the same or similar laws can be used to restrict otherwise legal firearms and ammunition limits while a citizen is excreting their right to self defense. I may be wrong, but I would have thought they would have tried this already.
