Maybe they finally got tired of keeping most of the stock in the back. This whole thing has been artificial. No gun store I go to has a lack of ammo. It only seems to be WalMart.
And to add insult to injury, at Walmart the employees play games alerting their buddies, so no matter what day or time, they are always "out" for the regular customer.
You'd think that after years of scarcity, they would have a sign up sheet so ALL customers can know that eventually they would be able to buy the stuff.
No such luck yet...
