Just to clarify, the picture he posted is not the buck that he shot. I think he just put that pic up to show his shot placement on his buck. Correct me if I'm wrong Jellio.
I really hope and THINK you will find your buck. Even if it was a gut shot; he should be dead by now. I hope you check near water while you're out there.
Another thing, don't put the bow away because of this incident. I know it's a confidence killer but you can't give up that easily. Bad shots/lost deer have happened (or will) to all of us. You just gotta keep at it.
Good luck finding your deer man. I feel if you truly put forth the effort to find this deer...you will. We want pics too.
