So I have been doing some thinking on which gun to put in my survival bag. I know I should have an AR with 6000 rounds and a FAL and 50 cal sniper and grenade launcher and what not. I am really looking to get a small caliber rifle or pistol. I am thinking some sort of .22 LR. I really need it to be light weight though. I also don't really want to carry a ton of weight in ammo. Any ideas? I just don't know about reliability and accuracy. What options should I look at. My backpack is 3800 cubic inches. The gun and ammo will be left in it all the time. I have plenty of zombie invasion guns.
