Splitting the pins due to being unsure about the distance to the target. Don't do it, you'll miss every time (I did anyway). Now I just pick a distance, pick ONE pin and let the arrow fly. It's a much more effective way to kill a deer.
Not waiting enough time to let the animal expire....for example....last year I made a pretty solid shot on my deer...Went over to where she was standing and had good blood right away. Well, you know how it gets, you start looking around. My arrow was only about 20 feet away but in finding it I bumped her. She had bedded only about 25 yards away from where i hit her. Granted, she only ran another 50 yards and expired but if I had simply waited and not been anxious to find my arrow/blood she would have expired quicker and not have had me bump her. So I guess my mistake was not in the shot but in having enough patience to not even move in for a bit.
Not taking the shot when you have it, just because it is early season.Learned that the hard way last year. 1st year hunting, 1hr45min into my 1st day I was full draw on a nice fat Muley doe, broadside @ 40yrds. I hesitated, then let her go. Never got within 65yrd of a deer the rest of the hunt...
