    I was just wondering if a guy with a 7rum with a 9 1/4 twist can shoot a 175 smk even though they recommend a 8.5. If so dose any body have any good loads.

    I don't know who recommends the 8.5 twist but the 1 in 9 or 1 in 9.25 is perfect !!!!

    At 1000 yards the 1 in 9.25 is the preferred twist in a 7 Rem Mag at 3100+ ft/sec and
    the rum will bump the velocity buy several hundred feet per second faster than the
    Rem Magnum.

    There are lots of powders that will do well in the big RUM 7828,H1000,Retumbo,H5010
    and H869.

    good luck.

    PS; The fast twist are for slower velocities in the smaller cases like 7/08 with heavy bullets.
    (2600 to 2800 ft/sec.

    My 7rum has a 9 twist and handles the 180 bergers just fine at about 3200fps.
    I agree with JE 175's should be no problem in a 9.25T.
