I would carry the G17. People killed alot of deer with calibers that we consider pretty anemic today. Inside of twenty yards a double lung shot with either is game over.
I carry a pistol when I hunt for protection against two legged predators. You never know who could be using your property for a meth lab or outdoor grow. A scope rifle is far from ideal up close and personal.
I dont know who started the rumor that deer were armored. They are not hard to kill.
