[size]But a disturbing TN trend is somewhat just the opposite of taking a true "cull" buck: Purposefully killing off the most outstanding antlered young bucks when they're only 1 1/2 to 2 1/2 yrs of age.[/size]
How's this happening? By the widespread embracing of antler restrictions in defining a "shooter" buck, most pointedly those such as "4 on a side" and/or "8 or 9 points or more". While such antler restrictions do allow more 1 1/2-yr-olds to survive to 2 1/2, they actually significantly INCREASE the harvest of the best antlered 1 1/2 and 2 1/2's. Across much of TN, we now have mainly the smallest antlered of bucks surviving to maturity, just the opposite of what happens with the true culling widespread in Texas.
I don't believe we have so much a problem with the killing of small-antlered bucks (locally called either culling or meat-hunting) now in TN. Our real problem that's preventing the larger scale production of high-scoring older bucks is the over-killing of the best of the best young bucks ---- just the opposite of true culling, as in Texas. The best practical solution to reverse this "antler high-grading" trend is simply to avoid killing any bucks before 3 1/2, regardless of their how big or how small their antlers.
In other words, use "age" as the first criteria in determining which buck is considered a "shooter", just like they do in Texas, whether it's for the purpose of true culling or for allowing an outstanding young buck to meet his potential.
Because truly outstanding antlered 2 1/2's are often easily mistaken for 3 1/2's, many hunters who have recognized the antler-high-grading issue, are now focusing on taking bucks 4 1/2 or older, i.e. a mistake is a 3 1/2 rather than that spectacular 2 1/2. The reward is a growing number of 4 1/2 and older bucks with truly top-end antlers, most of which had to first survive being truly top-end 2 1/2's.
