A 12" round group means you can be off 6" either way of your target. Most deer wont die if your 6" high, forward or low. I cant tell you to hunt, or not, but I think you know your answer Kevin. If you are set on hunting, then get your bow/arrows tuned and walk forward until you hit a 6" circle every shot. If that means your range is 10 yards, then so be it.
