LEARN to reload first.. the reload. You should never have this be an issue ever again. Its fun, almost as fun as shooting.
I am not sure reloading is the answer. You have components to assemble how many rounds? Whatever your answer, if I have that many LOADED rounds, who is in a better position? I love reloading, but I have no illusions that it is any more immune to shortages (panic or legislative) than the guy who gets his ammo at the store. If they legislate against ammo, do you really think they won't extend that to primers and powder? All the readers around here are in a primer panic mode.
