Bear,
Thanks for the advice. I thought about Retumbo, but I dropped a 70gr charge of 4831sc into a case. I would have to compress the living crap out of it to stuff the 150gr Partition into it with how deep I have to seat in order to be .020 off the lands. I have never messed with even a slightly compressed load, I just dont like the idea of the powder pushing back against the projectile, although I do realize many people have experienced great results with compressed loads.
My 270 wsm is also an Extreme Weather, I am very pleased with it so far, it is looking like a keeper(that would make my wife way too happy).
