I killed one close to that this year, maybe even a tad wider, and the taxi swears he is only 2.5 year old. I found it hard to believe. But it depends where you killed it. On the eastern shore of MD, they shoot a lot like that, that are 2.5 year old. But where I grew up in Eastern Ky, that would be a 3.5-4.5 year old deer.
