A four year old and a five year old are hard to judge unless you saw them the year before and new it was a four year old. Duhh right? Just sayin knowin the deer helps. Not always possible though. Alot of east tx. 4 yr olds carry the same antler mass and beam length. Tyically on the average. 4 in. Bases and 21 in. Beams. 5 year olds put on those longer beams and better antler mass. 4 yr. Olds are at 70 percent maturity, but put on alot of handsome body weight and muscle mass. The first year of the bull look. Cant say. Looks like a great buck.
Recognize that taking real away from real is ruining respect and genuine values in real life and in real wildlife. If you dont care to, you may have already become too corrupted by man's greed and unethical new ways.
