GB, today my local gun store was like yours - pretty much anything you want/need, a little short on a few things, and a couple of limits on quantities (3 boxes per caliber of handgun ammo, 1000 of each type of primer per customer).
But two weeks ago (and for the past 4 months or more), it was a different story - a few kinds of powder, a couple of calibers/weights of bullets, no primers, and no handgun ammo except .40 cal. Go figure - it's like the dam burst!
