That's interesting because my local discount store recently ran bare of most popular ammo. They had recovered long ago from the election shortage and were amply stocked for the last year. They even lifted their ammo limits per purchase. Usually there were dozens of boxes of Federal XM193 about $7/box as well as Federal and Remington bulk packs. And they usually have several 250 rd bulk packs of Remington UMC 9mm, .40 and .45.
I went in over the weekend to get some .38 and they had hardly anything in .223, 9mm, .40, .45ACP. Oddly, they finally did have UMC bulk packs of .380ACP.
I asked the counter lady when they are going to get resupplied and she said they can't get any in for some time (indeternminate). I passed it off to just a glitch in their ordering system, but I am hearing scattered reports of increased demand and dwindling supplies. Some places seem to still have lots in stock and others are marginal.
I am just going through my inventories this time of year and topping off on reloading components and some secondary cartridges, so it won't matter much to me if there is another shortage, I am set for a while. I think it best to try to gradually accumulate a buffer supply to carry through dry spells, rather than try to scramble just before another hits.
It will be interesting to see if the draw down in the military forces will result in more abundant supply of ammo commercially. One thing driving demand though is a flood of new shooters and more frequent shooters. We may have doubled or tripled the commercial market just from those new/frequent increases.
