Still one heck of a buck and he still might make it in the book even with the deductions.
Mule deer antlers bi fork, meaning they come off the skull and after the eye guard they fork, then each one of those beams, fork again, and a typical mule deer is a four point with eye guards.
Score or making the book isn't the most important thing in my book, a big mature deer like that is a trophy to anyone. He's one heck of a deer. Not too many people would pass him up! nice job.
