Well, that would be the first mistake. You should approacher her from her back/side as she lays on the ground. In the case of a buck the nicest way would be to grab a horn and pull him up and back if you can straddling a small tree with his rack. Works like a champ. BUT, if you're going to shoot, why not just pick the biggest target and run one right through the rib cage. You hit it you got deer even if it comes back to life and takes off running.
