I didn't want to just bump this thread, but I would like to add more info if needed. I have worked up a load with this powder using the 125 Grain Sierra FNHP moving at 2150 fps for short distance deer out of a 30-30 using a red dot. Works awesome!
I also have data with the 125 Grain Sierra FNHP @ 2500 fps with VV-N120. Just need to get that 110 Grain Semi-Jacketed HP moving. I have used H335, but didn't get good results. I know there is data for RL7 and this bullet. VV-N120 is close to RL7.
