You are wise to realize different neighborhoods have different deer management potential and therefore hunters should adjust their buck harvest criteria to fit where they are hunting. In general, I suggest hunters set their buck harvest goals to met the realistic potential of the area. A good rule of thumb is to attempt to harvest a buck that’s in the top 25% of the age class of bucks harvested in the area. For example if most bucks harvested where you hunt are one and two years old, and 25% or so are three years old or older, than set your goal to tag a three year old or older buck. I strongly believe hunting should be fun while hunters work to improve the local herd and habitat conditions.
The chest of the buck in your pictures sags below where his legs meets his shoulders. His neck merges with his chest at his brisket and his back and belly seem to sag. These are all signs of a mature buck. I estimate this buck is three or four and I’m leaning more toward four! Based on the description of the area you hunt, this buck would be on my wish list!
