338 rum load data needed

[tayhot]

Looking for loads for 338 rum, specifically for 300 gr Bergers. I have A few powders to use, retumbo, h1000, and 7828

I'm loven 90.5 gr of Retumbo right now for just over 2800 FPS with a 300 OTM in a 28in barrel.

Hmmmmm, two inches of barrel approach ~32FPS/inch not considering difference between Retumbo and 50 BMG and slight difference in charge weight and rifle/barrel differences. Interesting!

Thanks.

I'm running 90.0 grns Retumbo w/ 300 SMK. (sorry, Bergers are too long for my mags). Velocity for 5 measured 2780fps w/27 bbl.
