I stopped by the Academy in Gretna a few days ago on a whim. There were literally 4 guns in the display case, and almost no ammo on the shelves.
Did I miss the announcement about a zombie apocalypse or something?
Artificial panic buying.
I strolled into the local Academy one day when they first opened. Grabbed my limit of 9mm ammo and some 12ga, then overheard the gun counter clerk talking about how he had multiple people get denied the day before. The place just opened and there was already a line at the gun counter. At least 15 people looking at ammo with me.
If you've been under a rock, go look online. Ammo and guns are OOS nearly everywhere.
