That's not a deer, it's an alien, notice the yellow eyes! (lol)... it's been proven that aging deer doesn't really work, while you may be within a year or two... rarely will you get the exact age (unless you have their dentition, teeth, analyzed). Not really sure about scoring, not an expert in that area, but I'd guess low 100s (like 120s maybe?)
I would say that buck is about a year and a half and he would proably score around 115-120 proably in the 150's next year if he lives he looks nice
Nice young buck... nice symmetry but will score in the mid 90s... if you want a high score, let him walk a couple more years. His daddy is probably around somewhere.
I agree with Steve here except I have him in the 95-100" range... Without a broadside view, it's inconclusive to really tell his age however, he's NOT a 3.5 year old so either way, it's up to your personal goals to let him walk or not to age and grow.
