I doubt a broadhead would even penetrate far enough intothe skull to kill a deer. Never ever go for the head or neck with a bow. For one, deer can dodge the arrow from just 20 yds away, they usualy cant move out of the way fast enough if your going for vitals, but a head or neck shot at 20 yds will more than likely always cause a miss or worse, a wounded deer.
Always go for a broad side shot behind the shoulder with your bow, or quartering away. Quartering means a deer is not totally broadside, more like at a slight angle, qaurtering away would mean he's angling away from you, and quartering too is just the opposite. Quartering away shots with a bow are pretty good shots, you come in from behind the ribcage and go all the way up to the front and opposite shoulder.
