Not that i'm aware of.
If I was going to try loading it, I would start with low charges for 300gr bullets. If it has a true diameter of .452, and no driving bands, it's probably going to have a lot friction. Might be a decent candidate for A-1680, or something similar (CFE BLK or Shooter's world blackout).
