Need help aging this buck...

The property this buck is on is near Bastrop, TX...in Caldwell County.

I have two pics - one from October and one from December.

I'm estimating him at 5.5, but think he could be a 4.5 at the youngest. What's your guess???

4 based on the last pic.

4

5.....old enough

4 1/2... do I get a free hat?

I think 4.5-5.0, big bodied deer but also before full rut...
