    IMR 4064 in 6 CM w/ 105/107's


    Just wondering if anyone else has tried IMR 4064 in a 6 CM ? The Lyman LR Percussion Reloading handbook lists it.

    Pretty fast powder for a heavy 6mm. It could work but you won't be anywhere near filling the case.

    by my calculation 36 grains on the top end.
    The Dunning-Kruger effect is alive and well.

    The 6MM 105 & 107 will work fine if the twist rate is right, 1-7 have been used with great success.

    The Lyman LR Percussion Reloading handbook lists 37.0 gn as max. I'm run that with up to some 108 tipped "seconds" that Midway was selling. Cases showed no pressure signs that were shot out of Savage "Tactical". which has a 1-7.5 twist. Plus the Bbl. wasn't to hot to hold after 10 rounds, like it was with 40.5 of 4350.
