When I'd get in front of her she would start flailing about so I decided to shoot her
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.
I did approach from the back but moved around to possibly shoot in heart. That's when she would flail about. From the back, the best angle was a shot to the head/neck. Sorry, but last resort would be to grab ahold of a live, injured animal. Like I said, what good would it be for both of us to be injured/dead.
