Hunting with AK-47s is like fishing with dynamite. Yeah, it can be done, in fact, it makes things a lot easier, but on some level, you are missing the point...
No, not true at all. The AK-47 fires the 7.62x39 round, which ballistically is almost identical to the .30-30. Most states also have a magazine limit while hunting, so you can't use a 30 round magazine, either, but limited to 5. So I fail to see where you are "fishing with dynamite" with an AK.
But the AK itself is a decent hunting platform, and the cartridge is a very decent hunting cartridge.
Now, the AR platform with it's 5.56 or .223 round, that is not a legal caliber in most states. So the proper statement would be "you can't hunt with an AR."
But you can get the AR platform in other calibers such as .300 Blackout that is another dandy deer round.
