I try to aim for the spine, that way if I am high it's a miss, but if low, hits center shoulder. Running I only go for head shots. Which are hit/miss or if I fail to keep rifle moving I end up with neck or shoulder shot. Haven't had any escape yet, except for one which was a total miss, gave him a dirt bath. Using shooting stix rifle slipped off handguards onto barrel nut which I shot under yote. Big ball of dirt in the air, by the time it cleared Houdini vanished.
