This will all stop when folks stop buying ammo at such ridiculous prices.
We (gun owners in general) ultimately control the price of ammo.
If some of us continue to buy ammo at these prices, the folks selling it at these prices would be foolish to lower their prices. That is afterall, the point of a business- to make as much profit as possible per unit of merchandise. If the market will bear it, they will charge it.
On the other hand, if those purchasing ammo at these elevated levels were to stop doing so, the folks selling it must then lower their prices to bring us back into the marketplace.
Will this happen? Sure, but not until those panicked by the current state of affairs either run out of money or come to the realization that ammo supply will return to their shelves if they just let up a little.
