Frank, maybe the hunters 30 years ago themselves did not take airguns seriously as a hunting weapon and this fact reflected on jurisdiction and no rules about airguns in many states. Anyway, I think if the hunters decide to take a stand, they can make some States enact laws about airguns through the NRA (as Tim suggested in another thread). I think there should be some common rules which may vary slightly from East to West coast depending on the game.
