I would have guessed the main beams longer than 22" but I guess thats why its impossible to get a accurate score from a pic, you can't see the subtle curves of the main beams which can really make or break a score. No matter what that buck scores, 150's, 160's, 170's, he is a brute and I wouldn't hesitate puttin an arrow through him.

On a side note, my buddy and I were discussing our "perfect buck" just last week and that pic is him. I told my buddy that my ideal buck would be a typical 6 point that doesn't have one defining characteristic (giant spread or huge tines or super massive) but he would be good all around and that buck is him, good mass, good tine length, good width, you can't ask for much more than that.
