I have killed one mature buck that I knew was in the neighborhood. However I was not specifically hunting that buck, just any good one that came by.

Actually I guess I should make that 2. The first one I saw crossing the road. The second one I got a trail cam pic 2 weeks before I killed him. Again not really hunting that particular buck. Just hunting a good looking spot.

I don't target a specific buck, rather a class of bucks. Mature bucks over 130" or so.
