Yeah, I know what you mean. My brother-in-law has a Marlin 1894 in .357 Magnum that I have been trying to buy for years. Sweet little rifle.
As to "survival", I generally picture "living off the land", for which a .22 magnum would be hard to beat. Perfect for small game, with careful placement, adequate for deer, etc, and accurate to ~150 yards if needed to defend oneself against two-legged predators. Several handguns to choose from in .22 mag, so you could have a revolver and rifle in the same caliber, and you can easily stuff a couple hundred rounds of ammo in a pocket.
