I just got off the phone from Hornady. They said they developed the 150 for the 7mm-08 and the .280 Rem.
They suggested using Nosler's data for the 150 NP with Hunter, max of 49.5 grains, velocity 2869 but from a 26" tube. Adjusted down 90 fps should put me close to 2780. They really like Varget with a max of 39 grains for 2700.
It's a start.
