Honestly from everything I've ever heard, if you could only take one gun into a (living off the land) survival type situation, it should be a .22! You can feed your family, it's fairly quiet, and ammo is cheap. Comments like that make you sound foolish and uneducated. If .22 is so terrible why is it so popular? It is likely the first caliber most people will ever shoot, not to mention it is great for small game.
Psalm 82:4 Rescue the weak and the needy; deliver them from the hand of the wicked.
3 And you shall tread down the wicked, for they will be ashes under the soles of your feet, on the day when I act, says the Lord of hosts.
