I just picked up a few #'s of Norma MRP, and plan on running the 208 to 230 with it depending on how it shoots. I REALLY need some load data. Thanks. AS.
Norma MRP, need direction for 208's up to 230's in .300. WIN MAG

Here ya go Todd.
300 Winchester Magnum - heavy - Norma
This is one company that has accurate data, be careful around max, they push the envelope!
Another powder of theirs, 217 works really well on overbores, not sure if 300 mag is in that group, but it's slower than MRP.

Thanks Miles. Boy I'm glad only loaded six of them up otherwise I'd be pulling bullets left and right.
