Are you saying like your bush plane crashed or are you talking nuclear holocost?

If I had to surrvive in the wilderness,thats easy.I would take one Ruger single six in 22 LR and 22 WM.I could carry probaly 500 rounds of Both.

If this is a military kind of senerio,Russian sks in 7.62x54.Then that way I could take my ammo from dead guys and keep getting new guns in the proccess.
