It's extremely difficult to judge from that photo angle. Need other pics from different angles to better determine shape(length), mass, etc. Having said that he has decent prongs high on the horn putting them in the 3rd quarter for scoring which is a real plus. Best guess is 76-78". A real dandy and a trophy in most fellas eyes. He'd make a handsome mount and unless someone is an experienced "goat" hunter and won't settle for anything less than 80" it would be very difficult to let him walk. That and of course a lot would be considered where you're hunting. Are you in an area that is "premium" such as a Red Desert unit in Wyoming, or a special tag in the Southwest? If that is the case then you pass. None the less, he is a very good buck worthy of a spot on most everyones wall.
