Art asks the $64,000 question: Survive how? You gonna stay in town where survival may mainly mean defending yourself, or you heading for the boonies? Two totally different scenarios requiring two totally different types of equipment.
I personally would head for the boonies since a) I know how to survive there and b) I already live at the edge of the boonies. As such, a semi-auto with a pistol grip and an obstrusive banana clip hanging from the receiver would be my very last choice.
In the boonies, or at least my boonies, I'd not expect to see much human activity since mesquites, cactus, and rattlesnakes don't appeal to the general public. So, this eliminates my need for a true fighting rifle. So, +1 for the
Scout Rifle. This is my first and second choices:
Chambered in 308 either of these rifles (the top one, by the way, is mine
) would be easy to feed, handle large game and if needed would be OK for defense at longer ranges.
Now, if you're a handloader, you can carry your full power hunting/defense loads and regulate your scope for them. Then you'd also carry light cast bullet loads for small game which would be regulated to shot with the open sights. (The scope, with the proper mount can be removed and re-mounted with a coin)
If you're not a handloader and depend on factory ammo, then with the rifle I'd want one of these:
32 ACP, OR 30 Carbine, OR 32 Short Colt, 32 Long or 32 H&R in: 308 Winchester
A couple hundred rounds of 32 ACP doesn't weigh much and would be OK for small game. Again, regulate the open sights for the handgun round and you're set.
I have one of the old Savage 24's in 22LR/.410 and it's as handy of a small game hunting firearm as I've ever owned, but I think it'd be impractical for use in situations where an adversary might weigh more than me.
Also, I
might also carry a good quality semi-auto in 22LR for small game.
