I think it has something to do with the 'just-in-time logistics' system not being able to keep up with spikes in demand. Every hour a box of ammo sits on the shelf, the company is essentially losing money on it, so they aspire to minimize the turnover time with new stock arriving just in time. Plus, I'm betting that ammo is pretty far down the priority list with respect to moneymaking as far as Walmart is concerned. They simply do too much business in other product areas for it to count much.
Which isn't to say that the Walmart logistical system isn't impressive. It's exactly the opposite. But if the system has to choose between item A, which sells at price B and rate C, and item X, which sells at price 3B and rate 5C, it's going to pick the latter.
Edit: Well, that, and the overall spike in demand, lull in supply as component prices, go up, etc.
