Who says he was targeting that specific place? In fact, it seems likely that the target was his head and the shooter pulled the shot a bit but was still within tolerances (with a 1 MOA scope @ 200 yards you're only looking at 2" of variance).

I've killed deer beyond 200 yards sitting on a stump with a cheap rifle, it's not actually that hard if you've shot a bit before. The nerves though... you're right there, I couldn't imagine.
