When you come upon a deer you were tracking and it is laying down and not dead, do not hesitate, put another round into it where it will do the most good. In addition, when approaching it have your rifle ready to shoot so you are not caught flat footed. If you are in unfamiliar territory I suggest carrying a GPS to if you get hopelessly turned around all you have to do is hit home or return and it will take you to where you started.
