i dont worry about this. I am curious as to how many of ya have actualy had this happen with a xbow. What the range was. did the deer know you were there. It seems to me like some folk worry about this to the point of making me wonder if they ever pull the trigger. I believe the closer you are the faster the deer reacts to the sound based on reflexes, the farther away, they turn to see what that noise is. Not trying to start a debate, just curius about other hunters personal experiances, oh yea, just what you have seen, no scientific data please.
