One of the issues I'm seeing is that the above average 2 1/2's are the ones with the most potential to grow into what most would call "monster" bucks, yet they are the very 2 1/2's most hunters have the greatest challenge in letting walk. Meanwhile, those below average 2 1/2's are given multiple passes by multiple hunters, and end up composing more of the "older" buck population.
Hypothetical Examples:
Buck 1 scores about 75" as a 2 1/2-yr-old typical 6-point.
A growing number of hunters eagerly let this one walk.
Buck 1 survives to 3 1/2, and becomes a "nice" 101" 8-pointer.
But again, many hunters are using a personal standard of say 120" in defining a buck they consider a "shooter". So he survives to 4 1/2.
Buck 1 scores 120" as a 4 1/2-yr-old typical 8-pointer.
Let's say he survives again to 5 1/2.
Buck 1 scores about 130" as a 5 1/2-yr-old typical 8-pointer.
[size]Buck 2[/size] scores about 110" as a 2 1/2-yr-old typical 8-point.
Still having a somewhat relatively small "adolescent" body frame, his antlers may "appear" larger (may "look" more like a 120).
Many hunters who are trying to use 120 or so in defining their minimum "shooter" buck, they don't let this genetically superior antlered buck walk (and are often disappointed with the major "ground shrinkage").
But "what if" Buck 2 were allowed to survive to maturity?
Should Buck 2 survive to 3 1/2, he likely becomes a "nice" 135-inch 10-pointer.
Say he survives to 4 1/2.
Buck 2 likely scores 145-plus as a 4 1/2-yr-old typical 10-pointer.
Let's say he survives again to 5 1/2.
Buck 2 LIKELY SCORES OVER 150" as a 5 1/2-yr-old typical 10-pointer.
If our stated goal is harvesting older bucks with larger antlers, might that be better achieved with a focus on just passing up all young bucks, particularly those best-antlered 2 1/2's?
In other words, focus more on age than antlers, and avoid taking ANY bucks younger than 4 1/2?
As a side benefit, you will seldom experience "ground shrinkage" when you focus on harvesting only 4 1/2 or older bucks. In fact, you often experience just the opposite, i.e. the antlers are larger than you expected (since the buck is larger-bodied making his antlers "appear" smaller).
