I've always steered toward common calibers simply because the ammo tends to be cheaper. During the last ammo shortage, I had only a slight problem finding .38/45 Auto/40 S&W. As for the whole aspect of ammo shortage caused by economic/social collapse, I would just make sure you had a 1,000 or so rounds per caliber squirreled away, which comes full circle back to common calibers being cheaper in general, which makes it easier to stockpile. My 2 cents.
