There are a bunch of 312 Hornady 174 flat base bullets coming onto the market right now in 100 count boxes - I've seen them in a few places locally. Not an answer to your question, but just an FYI. Also wondering if we could get the Chinese (locally the source of a lot of 762x54 ammo) to sell us just the bullets. They're already producing them, they don't have to change anything, and they could sell a sh*t ton. Sounds like someone with the right connections could make a bunch of money.
