I asked my friends what kind of gun they would prefer and naturally they split. One group is shotgun fans who claim that this is the best survival gun. You can hunt big game and birds with one gun. Other group says that in survival situation every shot counts and long range rifle with optical sight is necessary. The idea behind it is to kill effectively with one shot from long range. Preferred caliber is 7.62 mm (NATO size ) with heavy bullet, bolt action single shot. In addition they advise to buy high precision weapon corrosion and rust resistant, which will operate without oil (important in the winter). Bullets are lighter then shotgun shells.

Whether to chose a rifle or shotgun for hunting depends on what type of game you intend on hunting. I personally believe you should at least one of each; preferably in a common caliber and that isn't too complicated. You should have a good supply of ammo and spare parts, plus the knowledge on how to repair your weapon. Reloading your own ammo is option also. A sidearm would be preferable also for when you can't carry a long arm. Whatever option you chose you need to get training and practice beforehand. I don't think you need to get decked out like Rambo unless you feel it is necessary. Just stating on own opinion.
