RE: Neck shot
Buck fever caused me to put an arrow down into the windpipe ofa strong buck a couple years ago. Lot's of blood, but it was just the windpipe and not the juggular. Tracked it a very long ways and searched day after day for a week. The deer died 2-3 weeks later and was found by a neighbor. I was aiming at the lungs but the combination of me shaking profusely and the deer turning the instant I shot cause me to be off by a lot. I will never aim at the neck on purpose with a bow. I didn't realize how bad I was shaking until after I release the arrow and watch the deer run out of sight. Those big bucks really make my heart rate climb! Gotta love this sport...and try to be as ethical as possible with shot placement so these magnificient animals have to suffer as little as possible.
Everyone makes mistakes and somtimes they get lucky. If you are one that gets lucky to hit the deer through the juggular and are able to recover it, please don't think you will be able to hit that same spot every time. Lungs/chest cavity is a lot bigger of a target where you can still be off by just a little bit and make a good shot.
