It appears the new world record Rocky Mountain Elk was shot on the last day of the year and season in Washington.
The guy that shot the Bull has 86 Bulls under his belt, 12 over 400” and has completed the NA 29 with his bow.
The hunter mentions AZ as where he expected to see the next world record bull come from.
The Spider bull was the previous record and came from Utah.
Pretty good write up of went down in the link.
