Pure supply and demand. In part, I blame panic buying, which plays right into the hands of the anti-gunners. Scare people into believing something bad will happen and they will get unnerved and go to pieces. Instead of keeping clear heads, gun owners are trying to snap up everything off the shelf and the result is they are causing unnecessary shortages. If cooler heads prevailed, there would be plenty of supply. Of course, the greed factor is in play. Retailers and private sellers are gauging on not only ammo but mags, AR's, even .22 rifles and handguns, exploiting the situation.
