Used casings?
The vast majority of factory ammo is NEW, with all new components.
Military casings are usually sold to clearing house and dealers for private reloading.
Like other commodities, new components are in competition with government demand for powder, primers, brass, copper and lead.
then what I read was wrong and i was wrongly informed. my apologizes.
I also heard it’s really hard to find teleprompters these days as birak has cornered the market on them.
