IMO he is a "solid bull". @26Reload nailed it and he needs to be ground checked! I really don't think grandpa will be disappointed at all. He seems to be blocky and big bodied bull. The inches only tell part of the hunt. Your scouting, your desire to "guide" grandpa to a nice bull is what life is all about! The hunt is also a lifetime hunt for you as well. Not many of us have chance to hunt with our grandpas. I was never fortunate to do so and wish you much success.I don't want to make this all about inches but he's been accumulating points for this hunt since before I was even born and I want him to come away from this hunt with a solid trophy and an impressive number to tell people.
Go hunting, bring the story back to us so we can all enjoy "the hunt".!
