I had to do some traveling for work in the past week so I checked out a few places. The reloading store in St Louis (can't remember the name) had Accurate Magnum, and Reloader 23. Unfortunately I don't have any loads for those powders so I didn't want to spend the money on something that might not shoot.
Franklin's Gun Store in TN had a pretty well stocked wall of ammo, but nothing you really want. (Like they had 223 and 9mm but it was only brands I've never heard of)
In Story City Iowa they had a pound of 4831ssc and if I remember right, a 8 pounder of 7828. No common calibers except for 44 special, but all the uncommon stuff was in stock.
All of the gun stores mentioned said they haven't gotten a shipment of primers since at least February last year. One of them said December 2019.
Bass pro shops in Altoona Iowa had a couple cases of primers due to mismanagement. Apparently everyone thought that those cases were for a different department and no one claimed them. One guy pulled out his knife and opened a box and they were full of primers, and the guy from the gun counter opened the rest and said limit 1 per customer. I grabbed a brick of Federal large magnum primers, they were all gone in 20 minutes.
The bullets I like to use aren't really cheap; so they've been pretty well in stock this whole time. (.308 caliber Nosler 210 ABLR, 230gr ATip, .257 caliber 100 gr partition)
But I am a bit scared. The only magnum powder I have left is 8 pounds of US 869, 2 pounds of RL19, and 1 pound of 4831. I was pretty well stocked before the pandemic but since I've been loading and shooting I've completely ran out of H1000 and N570.
