Ive seen alot of people take out young deer like that because the rack was crap. I personaly dont think you should even consider culling a buck until he hits a minimum of 3.5 years old. Ive had 2.5 year old 8 pointers that would easily make pope and young with bodies that might field dress 150lbs. Ive also had 3.5 to 4.5 year old 8 pointers that might score 120inches but would easily field dress 200+ pounds. The point is a yound buck with a big rack is a no brainer, he is gonna get big. A young buck with a small rack might turn out to be a good deer he just needs to get old enough. Some deer seem to put more energy into growing their bodies the first 3 years than others, it doesnt mean he wont be P&Y when he hits maturity.
