Why do you think folks are out buying up guns, and ammo? It's because they believe/think that Obozo will ban both guns, and ammo. I don't think that it's only the average citizen, but the gun, and ammo manufactures are afraid of the same thing. Suppose Obozo bans the amount of ammo you can have, ammo manufactures that are burning up their equipment just might get stuck with a ton of ammo that they can no longer sell. If I was making ammo, and worried about this, I would be making a lot less ammo, just barely keeping up with demand.
What's happening right now is that some of us have been stocking up for years now, and we aren't buying in bulk too much. But there are those that have recently woke up to the realization that this government will, and is, trying to ban guns, and ammo. These folks don't have a stock pile, so they are buying up everything they can find. The ammo companies are taking it slow, and easy, so as not to get caught with a bunch of stuff they can't sell.
