Most people slamming shots from 150 yards and up at a running animal don't even know if they hit it or not. They may have hit it somewhere other than a vital shot and the animal is running around wounded and will most likely die later. This is the reason i quite gun hunting and went back to archery. It just isn't safe with guys winging bullets all over the woods!!

Either way better luck next time. It comes with time but you will need to be able to calm yourself down and get a steady rest to shoot from and that shot can be done with one safe shot.
