If you question it, why use it? Obviously there are guns out there that would do a better job... why not use them instead? A lever-action 30-30 is pretty cheap, and proven to harvest deer.
I've seen a .410 slug drop a deer with 1 shot, but it was extremely close and the guy hit the deer in the neck, I doubt that was where he was even aiming. So yes it'll do it, but I doubt I'd hand it out to every Tom, Dick, and Harry that wanted to hunt on my land.
Freedom's just a word. If I'm gonna die for a word, my word is jello...
