Part of the problem is indeed the “sure I’ll pay out my wazoo” mentality. That’s not all of the problem though.
The pandemic hit every industry, including ammunition manufacturing. Lower staffing - especially with a very sensitive manufacturing process like primers - means that output dropped. But contracts don’t care about pandemics, and so contracts were fulfilled with (most of) the primer output most makers could manage.
And then “Joe Panic Buyer”, figured it was the ammo-pocalypse and mortgaged his trailer to buy everything he could. Loaded ammunition, components, everything. And that snowballed.
If I could find them, I’d buy a couple thousand small pistol and one k of large pistol. One brick at a time would be fine, too. Then I’d stop until I was starting to run really low. The trouble is that old Mr. Panic Buyer is still convinced we’re in the ammo-pocalypse, and until the bank takes his trailer, he’s going to keep stacking it deeper and deeper, like any good hoarder would. And he’s up 24/7 refreshing those web sites to see when stuff is in stock so he can buy them out. Again.
