A severe shortage is being reported in US too . It's mostly hypothetical though .
Well, to the contrary, it's mostly fact. Looking on the shelves, there are no primers for sale (except for a couple of boxes for 50 BMG, as if I need that!), hardly any powder, and the only ammunition is for some obscure hunting rifle cartridges.
Anything like 9mm, 45 Auto, 10 mm, 357, and 44 Mag is only a distant memory. I have seen an occasional box of 32 Auto, though that's only because it's not in much demand.
The shelves, in fact, look like those farmers' houses during the Dust Bowl days, when locusts would devour everything, even the curtains on the windows.
As the video said, new gun owners are buying and impacting the supply. But especially, hoarders are impacting the supply., but even more so, speculators are also buying up everything so as to profit from the situation. Reloading supplies, such as primers and powder, are unavailable because ammunition manufacturing companies are using these components themselves, to satisfy the demand for ammunition.
This is not all. When I go to the website of our local store (it is small, so the normal stock isn't great and having a lot of different models shipped from central stock is common), Most ever model of handgun that might remotely be considered for personal defense is sold out. I was looking at the Ruger Security 9 9mm semiauto, and Ruger looks to be producing those as fast as possible and letting most of their other line go until later.
I keep an eye out for interesting large bore cartridge arms from the 1860 - 1880 era. I don't have the budget to buy right now, but nobody else seems to be buying these guns either, and I've seen asking prices reduced (though, unfortunately, not enough to convince my Wife that now is the time to buy!) So, as I said, folks are grabbing up the more defense-oriented weapons, including "black rifles."
What I'd like to see is for something to happen that would cause prices on guns, ammo, and components to fall very drastically. Then all of these "capitalists" would be left with garages full of their hoarding, and they would have a lot of money tied up in something worth a lot less than they paid for it. (Folks here are doing the same thing with toilet paper and hand sanitizer. I wish the same ill on them, too.) Someone making a reasonable profit is one thing, but taking advantage of someone in need is not something I like. As some videos have suggested, I've noted those stores that I know are gouging, and determined that I won't buy from them again.
I can't imagine that the global situation is much different. Most of our ammunition here is made overseas, by companies like Sellier & Ballot, PPU, and others. Wolf and the other Russian brands also supply a lot of ammo. (Though, I wish I could find that 7.62x54r Barnaul ammo. Nobody even stocks it anymore, it seems.) So, with gun and ammo manufacturing being a global industry now, I can't see how things would be too much different anywhere else.
