It's happening everywhere. A buddy of mine ordered a large amount of 223 earlier this week from Max Prarie Wings in AR, it was sold as in stock, he paid via online and was given a ship date. Then the next day he was notified "no dice", refunded and given no other info.
Folks TOTALLY over-reacting on this ammo crap, especially for a pissant 223. But with the prices this crap is bringing I can see why EVERY dealer (large AND small) are pulling their sales and saving their bulk orders to bust up and sell for more money at higher price (per piece). It's called the free market and they had no idea 10 days ago anything like Newtown would happen and everyone would start acting like morons over ARs and ammo! Don't blame the gunmakers, dealers. Blame the pinkolibs for their chest pumping and the "skeert public" for reacting like children!
