From those pics it's hard to get an accurate score. Preferably you would want a direct side profile of both sides and a straight on...once it grows non-typical points you may need more angles.. Typically on those bigger bucks the best you can hope for is within 10 inches....from those pics (which are not optimum for scoring) on the conservative side I would have him at 185 but I can see 195..I kept hearing 204 - 208 which also probably skewed my bias.. Was still not able to come up with 200+ no matter how I looked at it (but could have been possible that I was misjudging something). There is one thing glaringly apparent from those pics: That buck is exceptional. No score needed to see that.
Glad a respectable man killed him. Congrats to the hunter!
