A buck was killed last year at our camp that had a high broadhead wound, above the shoulder pass through, and a low brisket graze. We border some state land. The deer was moving as though it had never been shot and the wounds were not even noticed until it was back at camp. Many grazed and non vital hit deer (bow) survive and never have any implications from them. Dont be to hard on your self as the shot sounds like nothing more than a graze or super ficial wound and should be fine. If someone has never done it, they haven't hunted long enough.
