Ok so maybe not Zombies but how about a huge natural disaster or civil disorder anyway it all goes to hell in a handbag. You know no power or water and its everyone for them selves. You only have what's on you back. You have to bugout grab what you can and make tracks. A pack each and a firearm.
What do you grab out of your gun cabinet. Not what you would like to have with you but what you can lay your hands on at a moments notice.
I would grab either my 10/22 Ruger or Marlin 39A lever.22 Why? Light to carry, high capacity, ammo is light to carry and I heaps of it. Both quiet and can be used to take small game and birds for food and at a pinch can be used for self defense. Yeah sure the 7mm Mag would be nice but lets get real its heavy and how much ammo can you carry same goes for the pump action Shotgun
