VV powder loads for 7RM

[RB II]

QL data for each powder attached. Start low and proceed at your own risk. I ran each powder up to just below max pressure using QL presets. I assumed a 24" barrel.

N565 and N570 give you more speed, but the loads will be compressed. As for temp sensitivity, I'm not seeing a lot of variation between these three powders. QL uses 70 degrees as a preset. When I up the temp up to 90, the pressure increases on max pressure loads are surprisingly similar (N560-2,424 psi, N565-2,548 psi and N570-2,868 psi).

I think N560 is your huckleberry.

Man, that is awesome data. Thank you very much!!! For sure the 560 will be up first.
