I shot a deer in the head once, that's not where I was aiming. The deer, on an icy steep slope, caught me in motion and must have lost his footing with its hind legs. It pivoted around its front feet, instead of jumping the string as they usually do. The arrow caught the deer behind the ear. It went down in 60 yards. Never ever take a head shot. Most of the time it will go bad, like the buck that was running around with an expandable broadhead in the back of its skull one year, near where I hunt.
