I want to shoot my .308 bolt gun & AR10 off a backpack (not at the same time). I have a place all to myself where I can shoot steel out to about 800 yards from a number of directions. I want to walk out with the gun and backpack for the day and shoot at different distances. The backpack would need to hold magazines/ammo, range finder, IFAK, binoculars, knife, food, water, etc. for the day. I may supplement it with a chest rig for the AR10.
Right now I have an old LAPG 3 day pack I was thinking of using, but it may be too big and too cheap for this use. What backpack do you guys recommend?
