RE: am i a bad hunter
All I can say is success comes with experience. I went two years before ever shooting my first with a bow. I now will always get at least one with my bow each year. It also depends on conditions, when you get to hunt, and the herd in your area. My first two years were poor because I hunted land that was not very advantagious for bow hunting. I now have land that is great for bow hunting.
I guess what Im saying is success rate doesnt depend on the quality of the hunter, but on a gambit of factors.
Keep hunting, Keep practicing, Keep learning, and most of all Keep on hunting.
