I was guessing 4.5 and 140 as well. I don't want to shoot 3 year olds and his lack of mass was my main reason of concern.
Trying to get as many bucks pegged as possible on trail cams and trying to share with neighbors who are hopefully like minded and can start laying off the best 2 and 3 yr olds.
And location is northern IL as stated in profile.
I've been trying to hold out for 150+ size deer for several years, but knowing this deer is mature, I would take him given the chance.
Edit to say 1 minute after posting I have a buck down in my clover plot. I think it's a very mature one. Still sitting in my blind. It's my 1st buck in 6 years.
