I killed a 10 point last year like that. We just called him a pigmy buck. My buck was at least 4.5 years old and looked huge on trail cam pics because he was always alone and we never had anything to compare him to. Since his legs were so short, and his belly was sagging, he looked like a 180-200 pound deer on camera and his rack also looked bigger. He was still a nice buck but he only had a 14" inside spread. Another member killed a buck just like mine 2 years before I shot mine so there is definitely something genetic causing it.
