Looking at the side view Im going to say he's probably 15" from the base of his antler on the right side to the tip of the G2. (That's using the distance from the base of the antler to the eye saying it is 2") Take a piece of paper and lay it on the screen and mark the measurement then lay it across the rear view and you come up with right at 13" inside.
One thing I have learned is that people who tell you to shoot have nothing to loose. You are the one taking all the risk. My local GW told a room full of people when asked about width. He said if you have to ask the buck is to close to risk the chance. He does not cut any slack to experienced hunters.
That'a big ole deer. I'm willing to bet he is 14 inches or wider. We killed a 6 point last year that was 13 1/4" wide and it doesn't even come close to the one pictured. I would ground check him in a heart beat.
The side pic looks like he does. The rear pic looks like he might if his right antler sticks out further than his left as it appears, or is his right ear cocked? Front pic looks too close to call. I'd pass on him.
