    Any info on starting loads/powders/primers and tricks for the 257Weatherby would be great. Looking to shoot 115 Bergers.

    Try contacting 115vld. He shot this combination for a while and did very well with it.

    Well thay may be hard to get to shoot but thay are the best .25cal bullet as far as drop and drift.Unless you go wildcat.

    My load is.
    H1000-73.0gr this is over book max for 115gr bullets and way over bergers max.
    OAL - 3.350
    Primer-RemMag

    I full lenght resize just enugh to bump the sholder about .002-.003.

    geting 3360fps on my prochrono.

    This is out of a limited run Remington sps in .257 Wetherby with a 26in bbl.

    The one I had build didn't have the Wby freebore I planned on shooting 115gr TSX and 66gr/IMR-7828 @ 3480fps gave me groups under 1/2".
