    Greetings,
    I have news. I have turned up some data on the 375 Express on Load data dot com. This is based in the 444 Marlin case which is basically a straight sided 8x57 case with a rim. The data largely supports the Barnes Data for the 9.5 and 9.3x57 rounds with 47 grains of IMR3031 producing2,300 fps with the 235 grain Speer and 43 grains of the same powder producing 2,087 fps with the 270 grain Hornady RN. Looks like IMR3031 is in the Goldilocks zone for the cartridge. The nearest powders from ADI are likely BM2 and BM8208.
    GPM.
