For SHTF, I would be reaching past my AR15's to grab my 12ga and 22 mag bolt gun. In SE Louisiana where I live there are very few long range shooting opportunities, and 000 Buck will take down anything on 4 legs within 30 yards. For small game nothing will compare to a 22 rim fire. Dirt cheap ammo and you can stock pile a butt load of it. That being said, I have a LAR-8 on order and will be setting aside 308 ammo from this day forward :).
