If you are at all unsure of your scope, before you go out again...sight it! Impossible to tell for us...I dont recall ever hitting a deer that reversed itself, they have allways gone forward. Still, you have doubt in your mind. Go back and check it out, then carefully check your guns zero. Then, in the future...remember the lesson. A shot not made is a good shot. In the future dont force an unnatural shooting positon. Pass on the shot.
