I prefer to age a deer by looking at its teeth.A buck may have large mass due to its genetics but still be relatively young when you look at his gummies. A friend of mine here has a little collection of about 8 jaws from deer ranked fawn and up. He has them all lined up on display in his house, kinda a neat idea if your wife will go for it. This guy is a bachelor so he can get away with it. The doctor in town here took a buck last week that had 15 scorable points on it, had h1's like pop cans and not a tooth left in the deers mouth. Eating him will be like chewin on a tire but who cares when the deer is a booney.
not sure if that was the question or not, hope it helps.
