    Is anyone loading for the .300 Weatherby using a 180 Nosler Partition?What are your powder recommendations out of a 26" barrel?How does the accuracy compare to a .300 Winchester Magnum?I have heard that the radius shoulder effects the accuracy potential of the Weatherby-true or false?I am thinking about a semi-custome build.Would hunting performance be that much better than a .300 Win.mag.?
    Thanks,
    Jimmy

    There are lots of great 30 magnums available
    and velocity is the major difference.

    For all out speed with big bullets the 30/378
    is hard to beat with the 300 rum next and then
    the 300weatherby to the 300 win mag.

    There are some wildcats mixed in but these
    require special loading and brass may be hard
    to find or expensive.

    The radius shoulders are not a problem.I have
    built quite a few weatherbys and the chamber
    fit and head space are the most important.

    All weatherbys have lots of freebore so they
    can be loaded very hot this also does not
    seem to be a problem if the chamber and
    headspace are tight.

    All of the big weatherbys have shot under
    a 1/2 moa and the best was a 30/378 that
    shot a .092 5 shot group @ 100yrds with
    a 200gr noz partition.

    The 300 rum has a good reputation for accuracy
    and doesent have a belt allowing it to be used
    with a standard mag bolt face like the win mag
    and the 300weatherby.

    With any 30 mag I recomend a heavy sporter barrel
    or larger( #5,#6 or a #7 taper unless you install
    a break.)at least 26"to 28" long.

    I hope this helps /ubbthreads/images/graemlins/smile.gif

    I am a gunsmith but I dont advertise because I prefer
    to build rifles one at a time. this way the client
    can have his/her rifle 30 daye,s from the day I
    receive all of the components(barrel,stock,action etc)

    By not trying to do to many I can concentrate on quality.

    I really like doing business in my area so I can go to the range with the customer and help with breakin and
    chronographing ."Its nice to be retired"

    Word of mouth keeps me busy so I dont advertise (no web page)

    I really enjoy this web site and have found some gunsmiths
    here that are a cut above most and seem to place the
    customer first.

    I started building rifles for my self because of poor
    quality and service from custom gun smiths, and enjoyed it so much I just kept on building for frends.

    After spending thousands of dollars and waiting 2to3 years
    to get a custom rifle built you should not have to fix any
    thing to be happy with your rifle.

    Long winded but if I can help just ask, I sure dont mind
    asking if I need some help.

    I have not encountered a 300 Wby Mark 5 yet that will not get 3300fps out of a 26" barrel using IMR-7828. I'm getting fair accuracy with 200 grain Accubonds going 3100fps with 7828 in my Accumark. Under 1 1/2" at 300 yards is the norm. I'm sure off a bench that would be a bit better. I shoot most of the time over a bag out the window of my van.
