We have killed 5 bucks 4.5 or older in the last 5 years and only 1 scored over 140 and he was the only 8pt but 7.5 years old. Using my trail cam pictures I have 6 bucks that I know are over 4.5 and only 1 will be over 140. The bucks where I hunt are 125-135 at 4.5 and only reach 140 around 6.5 years. I'm sure there are bucks that hit 140 at 4.5 but it would be the exception to the rule.
