Here's the thing man. You shouldn't see 12 boxes at your local Walmart You should be seeing pallets. Pallets and pallets and pallets stacked to the ceiling. In every major retail outfit ...
No idea what the generic, big-box type retailers might be doing. For arms, and particularly reloading supplies, the big-box joints aren't where I go. Though, I'm assuming they are experiencing similar general supply issues that most other gun shops are.
Wouldn't surprise me if the Walmarts of the U.S. don't have sufficient "pull" to get product for reloading, even ammo, right now. Early 2021, Academy had a handful of boxes of ammo in a common caliber ... but
Again, until the average shop begins to have dozens of boxes of primers there for a few weeks (beyond instantaneous demand that wipes out shelves full of stock these days), it'll still be what we've been experiencing. Once inventory begins sitting there for awhile at most shops, and more than just a few boxes, I'll begin to believe things are turning. Not until then. At Walmart or anywhere else.
It'd be nice to see proper inventories at even a few shops. Heck, even the big ones ought to have at least modest supplies of such stuff.
In a place in the Portland, Oregon, area about 10yrs ago, this large sporting goods place had a dozen long aisles full of ammo, with every conceivable caliber, often cases of the stuff, from the floor to shelves higher than I could reach. (Your "pallets and pallets full" situation.) Last I saw them, they had nearly nothing in the more-popular calibers and had effectively shut down half of those aisles for other products. In most shops this past 2yrs and more, irrespective of size, it's much like that. Far less space devoted, and vastly fewer items that sit for only brief periods of time.

Which suggests much going on with supplies, if even Walmarts of the retailing world can't wave a wand to get all they want.
Which was my point. Until I begin seeing dozens of 1000ct boxes of popular primers on the shelves of many reloading shops, including the tiny and the large shops, and so long as prices are frequently (even typically) north of $100/bx, I won't believe things are turning the corner.
But, yeah, once Walmart, BassPro, Dicks, etc, begin stocking more than rare quantities of such stuff, there won't be much hope for the market getting back to "normal."
