agreedI remember reading a study that basically said, by three years old, big deer have expressed most of their potential frame wise.
From then on additional growth is mostly mass and extras.
I couldn't find the study, but here's an interesting article on antler growth.
The keys to antler growth: Age, genetics, nutrition
3 big factors to take into considerationwww.gohunt.com
Lots of big young deer get killed because we equate antler size with age, and a fair amount of 5+ year old 140 to 150 class four points get passed so they can "grow up" when in reality that's all they will ever be.
Congrats again on an awesome buck, whatever the age he's a giant.
Sweet buck!!! Patience is key pretty much all time.
