I try to aim right above the elbow on a broadside deer, but yesterday morning that wasn't enough. Had to stop a buck in a shooting lane at 35 yards, and hit way high. Didn't look like the deer ducked at all and I was cursing myself all morning for making a terrible shot. Luckily had the shot on HD video, and watching in slow motion, the arrow went exactly where I aimed - but the buck ducked more than half a body length by the time the arrow got there. So, from now on, if I have to stop a deer at more than 25 yards I guess I'm gonna aim lower at the hairline.
