Due to massive social unrest, your city is burning to the ground. You and your loved ones decided it's time to bug out. All you have is a 9mm pistol and a decent supply of food and water. On your way to your pre-determined bug out location, you run into a family friend who wants to barter his firearms for food and water because he didn't see this coming. You have enough spare food and water to trade for only one weapon. A .22 long rifle, a 12 gauge shotgun or a bolt action .308 rifle. Each gun comes with a good supply of ammo.
