140" bucks are not common anywhere outside the Midwest (and not that common even there), but without question, Western KY produces more top-end bucks than most parts of TN, even looking at same-age bucks.
I disagree somewhat. I have been hunting in western KY for several years now. I would not say 140" are common, but it you want to say 130" and above, to 160 class bucks, Western KY sure has them. There has not been one year that I have not seen 1 or 2 giants killed (meaning 170" or better), First year there I saw a nontypical, grossed in the 230's, the Dan Hughes buck, 250's, was killed not to far from where we hunt talked to him, really nice guy, I measured a shed found near Cadiz, one side, 83", I could go and on. And for 130's to 160's class bucks, I see many killed in that range every season. 2 different seasons, on the farm we hunt and a farm or 2 beside it, there has been 6 or more bucks killed that measured from 130" to 160" in the first week of the season. My brother and myself killed a 130's and a 140's class buck on the same day out of the same tree, great memory for sure.
There have been some off years for us to, but every season, I see many super nice deer killed in Western KY. The area I hunt is surrounded by "if its brown, its down" guys. They kill every single deer they legally can. No telling how much better that area would be if they would let more young bucks walk.
Also, does that mean "everyone" kills a great buck every year or that everyone has killed one? Nope, not even close. Is there a pile of deer killed every year that are over 130"? For sure.
