If You hit the deer where You said You did the deer will die, but where He dies is the big question. When a deer is gut shot They usually bed down, and die in there bed. Usually within 150-200 yards from where You shoot them, but if You went looking for Him, and spooked Him out of His bed or in general He could have went in any direction with no blood trail to follow, and its hard to tell how far He'll go before stopping. I'd say put Your walking shoes on tommorow, because You've got a long walk looking around for that deer. I do believe You'll find Him though. Good Luck!
