Im looking for aaround 2900 to 3000fps with this older 200 NBT. I need to load with Varget. I have no R15. I'm looking for sor some, but hey. I did use R15/Varget interchangeably in my first 9.3x62 but don't want to interpolate for the 338 Win Mag. just want a comparable load to what R15 can give me? Thanks
