I've seen this deer a few times in the same drainage in the mountains. I've got some good pics of him but only seen him during winter months (Dec - March). I would love to find him during hunting season.
This buck below went 153" if I remember correctly... Super spindly but decent length where he needs it. The OP buck has better mass (+4"), a few more inches on width and slightly better mainbeams (1.5-2" per measurement = +5-7") plus a kicker (+3"). I see him being about 10-15" bigger than this buck in overall score, but I don't see 30+" of measurements to hit that 180"+ mark. Tricky buck and I wish we would have a chance to see an actual score on him!
