There's a lot of guys shooting RL-22 in the 270WSM with great results. RL-17 has worked for many as any 4350 or slower powder. Magpro was a standout as far as accuracy, velocity and consistency. AA3100 was just as good but was over 100fps slower, not that it matters, but I'll take it if its there. I also found that the 130gr NBT had the same POI as the 140gr NAB.
This is God's universe, and he has a plan. You might think that you have aa better plan, but you don't have a universe.
