The United States Supreme Court already defined (MANY years ago) the weapons under the 2nd Amendment. Notice, they say nothing of hunting or self-defense. BTW, AKs make good hog hunting rifles.
United States v. Miller (1939)
In the absence of any evidence tending to show that possession or use of a "shotgun having a barrel of less than eighteen inches in length" at this time has some reasonable relationship to the preservation or efficiency of a well regulated militia, we cannot say that the Second Amendment guarantees the right to keep and bear such an instrument.

Sawed off shotguns were used in WW1, so the court here on Miller 1939 was wrong as well.
