    Ross, what are the ballistics on each of these and are they all based on the 505 Gibbs just necked down and not shortened? What length barrel was used? What brass are you using and what is the C.O.L.? Who makes the dies and reamer? Did I forget anything?

    Thanks much, and nice rifles you got there too.

    Ross, I think we would all be interested in this one.

    Thanks for the interest. In all honesty
    the only serious work has been done with
    the 416 version. 28" Pac Nor tube mustered
    3021 with a 400 grain X. This load was
    very maximum.

    They are all based on the Gibbs case. We
    have a body reamer from Pacific Precision
    and we neck and throat these seperately.

    Currently the major problem with these rounds
    is obtaining a supply of high quality brass.

    Mast never seems to have it and there are
    rumours of a German firm producing it
    however I have not seen any.

    Time and workload constraints have prevented
    us from working with the other diameters
    but we hope to in the near future should
    a supply of quality brass become availalbe.

    Hope this helps.
