So you agree with using an AK-47 for hunting? Imagine how much of the deer would be left if you used it? I am guessing none 
1. A full auto no-shit Soviet Red Army Infantry AK-47 is illegal as hell in the USA
right now, without an anal exam of a background check and a $300 tax on top of whatever ungodly amount you'd have to pay for the weapon itself. The "AK-47s" available for (relatively) easy sale are semiautomatics. They are ugly and easily demonizable by those with an agenda (you, perhaps?) but mechanically inferior to a WW2 M-1 Garand in almost every respect (and you can -- still --buy those from the government!).
2. Any jackass who would empty a 30-round mag into a deer deserves the few pounds of usable meat he would find in the carcass. A well-placed, controlled three-round burst, on the other hand, wouldn't do any more damage than three rounds from a bolt-action Remington 870.
3. The Second Amendment isn't about
hunting, anyway. It's about ensuring that the People have access to weaponry sufficient to keep the government-- the People's servants and employees-- from getting too
uppity.
4. The American Way of Rights has never been about
need, either. The whole idea is that we have the right, the freedom, the liberty to do what we wanna, just because we wanna, with damfew restrictions that basically amount to "my right to swing my fist ends at the tip of your nose."
