The best solution is to avoid contributing to the problem in the first place.

In other words, buy ammo during times of relative peace/prosperity whenever possible. (If you can afford to buy even 1 box of ammo every paycheck, then do it.) That way, by the time of trouble inevitably occur, you'll have stockpiled more than enough ammo to get you through it.

Seriously, if everyone did this, then there probably wouldn't be any ammo shortages because ammo production would be ampted up at all times in order to meet demand and thus there would always be ammo on the shelf and everyone would have all the ammo they needed.
