You did say RIFLE....that rules out several states on your list. I've hunted KS every year since 2001,and have killed 150 - 160 class bucks each year except one. That year I slipped up and popped an eight point that scored 148! I lease my own land now,but have hunted with Kent and Kirby Buer near Concordia.... They kill 160's and better each year. Reasonably priced.
www.riverbluffhunting.com Great people. Best of luck to you! Here's a shot of my buck from this last season. He netted a shade under 165! Kansas is a magical place!
