Before anyone answers, review the moose ID pages here. Especially the infographic in the pink box in the lower right corner of page 1.
Consider that this is a bull from GMU13 taken under a harvest ticket for the rules.
FYI - I did not shoot this bull. The rack was found on the side of the road where it had bounced out of a rig. Cantwell troopers have the rack and are in contact with the hunter that took the bull.
I will post photos that include a tape measure once we play this game for a while.
