When you look at things objectively, there's nothing wrong and this is expected.
- Supply lines were significantly affected by covid; some operations slowed production or paused during this.
- Demand for the popular calibers- 9x19, .223/5.56, etc- went through the stratosphere, as millions of new buyers bought guns
We saw everything fly off the shelves, and what little remained went sky high. People paying over 30 cents a round for Tula 9mm, because that's all they could find.
Ammo making is not an unlimited thing, they have to pick and choose what they make. Given the enormous demand on those certain calibers, I don't doubt that many makers focused completely on just that, to meet demand and make maximum profit.
Now, we're starting to see daylight with those calibers. Prices on 9mm have dropped, to where we're now seeing name brands we recognize (Fiocchi, PMC etc) at under 30 cents a rd again. Not just steel Tula, or no-names like Turan or Belom, but stuff we shot before 2020.
I suspect 223 will creep down soon, too, as production begins to catch demand. It's beginning to, we're seeing a lot of PMC hitting the markets.
The problem for your 22-250 is that it's a niche rd, not one selling thousands of cases in a month; so it's been sidelined since this started. Whatever stock is out there was made before the panic, and no resources will be given to it until things settle out.
