SO you are sure you missed because you didn't hear any impact noise? Well here's the deal you need to get out there tomorrow look the whole area over to see if you find one drop of blood. Gut shot deer usually hunch when they get shot they don't kick. Blood could be very little of because many times the guts plug the hole. And my advice is don't shoot another deer until you either inspect your arrow or see the deer is not hurt. But tomorrow the right thing to do is spend a good amount of time to look for any sign of a wounded deer. Good luck to you. And limit your shots closer until you can trust yourself. What I don't get is you say you shot 40 deer with rifle but your getting buck fever and can't hold it together for a clean shot. Keep us updated! Work Hard you may find that buck and learn what happened.

Oh yeah, welcome to the forum.
