Rating him against bucks where I hunt I would give him about a 6-6.5, he is a nice looking buck that I would stick in a heart beat with a bow seeing as I have yet to kill my first buck with a bow, heck I would probably shoot him during gun season depending upon the property I was hunting.
I have seen numerous buck larger than him here, I killed an 8 point in 75 that had a 21 3/4 inch spread on the inside of his beams and the tines were about 17 inches, and the mass was a lot heavier, I had him mounted but never got him scored, he burnt up in a house fire in 82!
