Today after I got out of classes I drove home to head into the woods for the evening. My friend from college came along and we started out about 1:30 or so. It was windy and I was showing him where to hunt for the evening, so after that I continued walking to my stand. About 100 yards from where I left my friend I see two deer feeding on an oak flat about 75 yards away. Again, it was windy and they were feeding away from me so I slowy started stalking them trying to close the distance. I get within about 40 yards of them with no clear shot when I see that one of them is a nice 8 point or so. I position myself next to a tree and he turns and starts walking at asteady pace in my direction. He finally stops and walks behind a small group of trees so I come to full draw waiting for him to step out. Well, he does but he's still facing me and walking right at me, about 20 yards away. So i'm standing there at full draw watching him close the distance through my peep. I didn't want to take a head on shot because I wanted to wait for him to turn...but he kept walking. He had his head down so I had no shot at first, but then he finally lifted and stopped a mere 15 yards away. He still didn't have a clue I was there and looked my direction several times. So, afraid that he would continue walking RIGHT to me and not turning, I was afraid I would lose any chance I had with him if he got too close and spooked. So I hesitantly put the pins on his chest and let it fly...the arrow hit just to the inside of his left shoulder and he turned and ran away with the arrow sticking out of him. He ran about 80 yards or so and stopped for a few seconds, and then continued running. I didn't find any blood right where I shot him so I decided to leave and not push him and goback in the morning to look for him.Icouldn't tell exactly how much penetration the arrowhad but it didn't look like a lot. Again, I didn't want to take a shot like that but I didn't think I had much of an option, maybe that was my mistake. What do you guys think? Could I have did anything better and do you think that was a fatal wound?
