Ah man. I can guess that's a 4.5 year old big bodied east Texas buck. Nice buck for sure !! I m just guessing
I agree area makes a difference but couple of things make me say 3. 1. his legs look long 2. His brisket is tight to his chest 3. his belly is tight to his core. 4. back is not sagging
I'll say he is 3 not enough mass or belly to be an older deer I know some of the guys here know what a Dad body is, this deer doesn't have one yet.
