I would say he's gonna gross close to the 170 mark, but it's tough to tell without actually putting a tape to him. He's got nice tall tines, and good main beams, the only thing I can see that he is missing is a little small on mass. Mine grossed 167 1/8 and I 'd say they look a lot alike.
good luck with him, and can't wait to see you with your mitts around his antlers.
