I'm surprised on many of the guesses of this whitetail being so young.

Although it is rather difficult to try an attempt at a solid guess.. clearly the sagging belly shows this whitetail to be older than 3.5 yrs.

A 4.5 in the summer also very rarely shows such a pouch.. I would guess him older than 5 yrs.

Although maybe not much for antler growth.. they have little to do with age.

I would be proud to take him.. not because of "cull" either (I cringe at the term and even more at the miss-use of that term).. but because he's a great and mature animal and at his age will likely beat you.
