Even Sierra Bullets in Sedalia, Missouri is "out of stock" in 9mm bullets for reloading. And Sierra makes tons of bullets. Even rifle bullets for reloading is getting harder to find. Brass, primers and powder are a similar story.
Sierra does have "factory seconds" which may have a blemish of some kind, but totally usable and sold per pound. But you have to pick-up the factory seconds in person. No shipping.

Graf and Sons Reloading has the same issues. They do have some powders in stock, but no primers and no brass. At least for the 9mm.

So, with COVID and the uncertainty of politics and riots around the country, everyone if stocking up with ammo and reloading supplies.
Get in line.
