Tonight I was in my homemade permant treestand and finally got the opportunity to shoot a doe at 20 yards. I was a little nervous but steady. I drew and grunted, she stopped and offered a perfect broadside I released the arrow and it sailed just over the top of her back. Which is what? 3 or 4 inches higher than I aimed. She ran about 20 yards and stopped in the brush. Well a second doe and 3 yearlings were in the field behind me at the same time. They didn't bolt either. They just stood there and stomped and snorted looking around. So I notched a second arrow and drew on the second doe at 25 yards and the same thing happened just high over the front shoulder. I have praticed a great deal with my bow in my backyard and can make a kill shot anywhere inside 30 yards with it. So please advise me as to why I missed 2 shots in 2 minutes and what I might have done wrong. Thank you.
