Nemat, if you want a semi .22, then you cannot beat the Marlins. Better and cheaper than the 10/22, and no need for an aftermarket barrel. Far far FAR better, and cheaper than the Rem 597.
Model 60 if'n you want a tube mag:

Model 7000/795/70 if you want a clip mag in essentially the same gun:

You are definitely on the right track getting a .22 over a .30 cal rifle for a survival scenario. .22lr and 12 ga is all you'd need if you're not battling hoards of humanoid invaders, and even then it's still probably all you'd need. By most all accounts, the Marlins are more accurate than the 10/22 out of the box (mine is superbly accurate), equally reliable, and for $110 brand new for a wood/blue model 60, that's serious value. By most accounts, 597 are more often junk than not. Some people's work, but more people's don't run reliably without tweaking the mags. The model 70PSS Marlin is a take-down model, if that interests you.
