You would be better off asking on Sauber.com. I have never tried N133 but for me the most accurate powder with 39s was RE10X but the high node was way too hard on brass and the low node was not worth it. I am running 32s sbks with RE7 but the alliant powders are temp sensitive so if you go that route watch for pressure when it gets hot out.

N530 will get top end velocities and burns clean
