    Helping a Friend reload for his 375 H&H Magnum with Sierra King 250 grain bullets. Only powder available is Reloader 15, so I came up with 76 grains with online manuals.
    Anyone in the forum thinks this would be too hot of a load?
    I don't have A Sierra Bullets Reloading Manual to double check.

    I like IMR-4320 with 270 gr. spire points, Elk medicine
    250 gr. is pretty light for a 375
    Look at the online manuals
    I believe Sierra is online

    Thanks Badnova. Got some good data from handloads.com, I think 76 grains of RL15 will be good to try. Yeah, 250 grain bullets are light but is what this guy has available.

    I had a load with my 375 that was 76grs of RL15 with the old (non-TSX) 250gr Barnes. Did about 3/4" groups at 100. Then switched to the 260gr Accubonds with the same load, I think. Either way, both bullets did 2860fps average and shot well.
