They have leftovers like everyone else, so there wasn't a huge variety to choose from in things like typical hunting and pistol calibers. But other than a ton of shotgun and dangerous game ammo, there was also 5.56mm/.223, some .308 and 300 BLK, and Tula Ammo in "normal" calibers. Not all oddball stuff, but not like back when you could walk into a gun store and buy nearly any caliber you wanted either. These are the times we live in.
As long as people are willing to pay stupid high prices for ammo, other people will sell it for stupid high prices. It will start coming down later this year when the shelves start to fill up (and almost immediately empty out again I imagine) but it still won't be anywhere near the old "normal" for a long time, if ever. It is what it is.
