Very well could be. The Shoguns must be getting disturbed by all of the cases and cases of surplus ball ammo in 556, 762X39 and 308 getting shipped to mere peasants across the land. Must disturb them greatly.
Or, to turn the entire country into a "shotgun-only" zone for deer hunting, as is the bigger half (I did NOT say "better"!) of Michigan. Been that way for years. If you want to hunt South of a certain arbitrary line across the state, it's shotguns-only. That basically means getting up-close and personal with Mr. Bambi. A shotgun doesn't give you all that much more range than a bow, in the grand scheme of things.
This will of course cause the deer take to nosedive, because the closer you are to the deer, the more wary he is, and the harder he is to take. (A bit of a Catch-22 paradox inherent in the deal.)
It might be a good idea to point out the massive costs that will be incurred by the increased deer population that will be inevitable if they outlaw centerfire hunting ammunition.
Insurance rates will go up -- as will medical expenses, and time away from work, and, there will be a tragic loss of life. Deer are notorious for going over the hood, through the windshield, and into the car -- and then killing the occupants. No joke.
My wife hit a deer. Nicked it with the left headlight. It swung around into the driver-side door. Killed the deer. Wrecked the grille, fender, door, and warped the side of the car. Cost the insurance company a lot to repair (and there's been problems since, that ain't covered, of course). The damage looked minimal, since it was just a glancing blow, but the looks were deceptive.
That was a good car-deer accident. My wife was not injured, just shook up a lot, and the car wasn't totalled, although the ins. company did consider it for a while.
Bad car-deer wrecks happen all the time, and many lives are lost. Human lives.
It shouldn't be hard to cast this inevitable increase in deer population in a "for the children" light -- and what's more, it won't even be "spinning" it. It's the truth!
