X-Factor: Modern gun season opens tomorrow (Nov. 21) in Tennessee, and though the peak of the chasing action has probably come and gone in most parts of the Mid-South, the pickup breeding phase is a favored one among serious whitetail hunters for killing a true bruiser of a buck. Not only that, down in southwest Tennessee, peak conception dates run a little later, around the first of December. Hunters in the Memphis area probably haven't yet seen the best of the 2015 rut. Finally, another cold front is forecast to move through tomorrow, bringing with it the coldest weather of the season. There's still plenty of time to get out there and shoot a big old buck.
