    I was wondering if anyone has tried hogden hybrid 100v in a 375 Rum, 416 Rigby or Wby. It seems looking at the burn rate charts that it would be quite suitable for these cals.

    I guess that it isn't cost efficient, because of low volume, but manuals don't seem to have as much data on big bores.

    Since I want to spend some quality time with my big guns. I thought I would play with some different loads to create some of my own data. So if anyone has input on these cals. I would love to hear it.

    Also what powders are least sensitive to temp changes.

    I just built into 375 on a Remington 700 receiver and started to work up loads today.

    Aside from the usual suspects like 4350, two powders stood out in the pack in preliminary testing.

    100v was one of them...

    .375 H&H M700 -
    77.0 / 100V / 260gr Nosler Partition
    2775 fps, spread 3, s.d. 1, .773" @100yd

    FYI the other powder was N150. Very comparable results at 2800 ft./s with a standard deviation of 6.
