I shoot two deer that age in Kansas, Iowa, or Illinois and they would be 140"150" at least.
I hated this line then.. and still hate it today. I can take you to lots of areas in Illinois where a 4.5 doesn't gross the P&Y minimum. Some don't even gross 115". And I'm positively sure the same holds true in MANY of the other big buck states.
Personally I don't look at inches.. that's called vanity. When a whitetail reaches 3 or 4+ yrs. of age he's now in a different class and experience. He's "smarter" so to speak. Whether he has 50" of antler or 150" of antler he is still a mature whitetail and I will never dismiss a whitetail taken by any hunter of this caliber.
Inches do not make experience and brilliance. Age is the ultimate judge.
