Ammunition hoarding has apparently led to some unusual sourcing for new stock. A case (of ammo) in point:

Description:

Caliber 8mm Mauser (7.92mm) Ball. Manufactured in Iran in 1950’s when Iran was a friend and strong ally of the United States. Brass cases, FMJ, 198 gr., Lead core, Corrosive, Berdan, Packed, Loose, 5 rows of 200 rds each, 1000 rds in sealed zinc lined carton. Wt of case 60 lbs

(emphasis added)

The Ukrainian-made ammunition brand, Red Army Standard, is widely sold in the US these days.
