Most of my emergency plans are for "bugging in," so I don't worry much about ammo portability. Arizona's desert is not highly productive land, so I don't plan to live off of it (I don't want to have to shoot every hunter I see to make sure that I'll have game). I do make sure that my reloading gear works without electricity. That's mostly so I have something to do while waiting for the Return Of The World As We Know it.
