Hodgdon recently announced they would be releasing to the general public the powder that Hornady uses in the leverevolution & Superperformance ammo. May be a good idea to wait until that actually happens in January 2011 before developing any loads.

I use the bullet in my M94 pre 64 30-30 Winchester but would be curious to see how this powder will work. Hopefully better!
