That's a beautiful buck. My guess is 4/5 years of age. The burr looks to be that of a little older deer. I'm guessing 22/23 wide with the ears at 16/17 wide. The color and shape are unique or at least different than I'm used to. In 33 years on the same mountain, I've seen one or two bucks that had that dark chocolate brown color. Always heard that had to do with what they're rubbing there horns on. I've seen bucks taken from the Gig Harbor/Peninsula area that have almost red horns.
As far as that age class becoming the perfect Washington buck. With the Wolves, Cougars and Bears traipsing the landscape in numbers not seen in many many years, the only bucks left are this age class and older.
