I have an answer!
I sent an email to Hornady asking about the ammo. I was seeing at Graf's & Sons and here's what they said they have a contract deal with Graf's.
Hornady makes the bullets and ships them to Graf's, where they are loaded. So you can only buy new Hornday component ammo. for these obscure cartridges at Graf's.
Now I'm emailing Graf's to see if they can provide ballistic information. I'll keep you posted.
