Whatever happens, be it local, regional or national, the majority of folks to be effected will most likely be in cities, towns, etc. So, the physical size of a long gun can be important. Do you want something easy to manuver and maybe conceal, I do. Sure, there will be folks heading out into the boonies, seeking safety, but I believe most will not. I decided to go all 9mm, carbine and pistol to simplify things, but I'm beginning to see the case for a .22. You can carry a lot of .22 vs anything larger. If you think about it, if you have stockpiled 5K rounds of .223 or whatever, you are not going anywhere.
