Looking for a backpack to keep all my long range shooting equipment. I started with a gun, scope, ammo, and range finder which was easy enough. But now that we are getting into it a little deeper and trying to make some long range colt bore shots, my gear list is growing quickly (note books, pens, anometer/thermometer, ballistics tables, chronograph, calculator, GPS, etc). Been looking at 5.11 and Maxpedition bags. Don't necessarily want something huge, but big enough to carry all the gear and hike about a mile relatively comfortably is definitly a must. Have never bought a "good" pack, so i'm pretty clueless. Any help and direction would be appreciated. Thanks
