I'm convinced that much of what we see at shows these days is ammo that is been purchased at panic prices by folks who now are trying to make a profit on it. As a result, it is even more out of sight expensive than it would be otherwise.
Right now, I'm finding acceptable amounts (and prices) on .22LR at my gun shop, and I am confident that this will continue. I doubt if prices will ever come back down, but I think supply is much more available and the "new normal" is being established in both supply and demand.
No need to pay double-scalper prices at a gun show, online, or anywhere else anymore.
