Data for new powders with .375 H&H ?

Has anyone seen any reloading data for the .375 H&H using Win 780, IMR 4007 SSC, or Hodgdon Hybrid 100V?

Iâ€™m going to take the lack of response as a â€œNoâ€.

Maybe the new Barnes manual will have some data when it comes out. . .

According to the 2008 Hodgdon Annual Manual it's a brand new powder???

. . . at second glance their calling it Winchester "Supreme" 780

I'll have to check that out, Win used to have a powder #780 that was close to H450 speed, seems it disappeared mid- 70's. Do they list it as to speed and application?

Just went Hodgdons site, looks like they have re-invented H450/780(both discontinued) 4831 speed in a ball/spherical powder.
"H450: This relatively slow-burning spherical powder was designed to do the same kind of work that 4831 does" SOUNDS REAL CLOSE
