Okay, I have .22LR and 5.56/.223 covered. I'm thinking my next (and probably my last) rifle should be of a bigger caliber. I want a rifle chambered for shots of 400-600 yards or more and one that has enough stopping power for either whitetail or mule deer; I'm in Texas now, but will be moving to Arizona within the next few years. It's been years since my Colt 30/06 went down with the boat. I want to hunt again, but I'm out of touch with the new ballistics and calibers. Any recommendations would be appreciated....and this rifle could be "pre-owned" if any of you are looking to off anything good.
