Looking at the mass he has, he appears to be a mature buck. If I was on a “trophy” hunt, I would not consider him a trophy. He is a narrow 4x4 with brows, a sticker, and is mature. I would consider him a management buck. You probably would prefer to have a wider more classic looking Mulie breeding than this guy. With that said, someone who hasn’t killed a Mulie or many deer for that matter may consider him a trophy. And there would be nothing wrong with that. Beauty is in the eye of the beholder.
Best of luck with your management.
