The Associated Press published this earlier today. It would have been nice if they mentioned when the shortage would end.

There is no shortage. I have seen plenty of common calibers at the show and online. The prices are still ridiculous- that’s the problem.
Some calibers are still harder to get here in San Antonio. The good news is .223 is easy to get/find.
