John, Re; OP 200 Gr bullet. I am not familiar with the "GRT Data Base". Maximum ME is not the goal. Looking for accuracy. I have limited powders. N-570, Retumbo, Re-17 and Re-19. GOD Bless! Greg

Alliant used to list load data for the .308 Norma Magnum on their data page. That data is long gone.

I don't believe that the WSM will out perform the .308 Norma Magnum in Velocity. However the .300WSM is probably much more efficient. There is a difference in operating pressures. The old wildcat .30/338 Winchester Magnum is similar to the .308 Norma Magnum. Not as much ommph as the .300...

I have reviewed the data on Nosler web site using the 200 Gr bullet. I have Retumbo and N-570 and 6.5 StaBall powders on hand. Are these viable for this application? THANK YOU! GOD Bless!
