    Finally got some 210grain berger and need some load data. Also what dies everyone is liking for this round.

    Fed 215 GM or a CCI 250 primer.

    75 grans of H-1000 and work up.

    We found a sweet spot at 77.

    .005" into the lands.

    As for dies. I would recommend redding "S" type bushing dies and if the funds are available go with the micrometer neck sizing die, micrometer seating die and the body die to bump the necks back when needed. These dies capture the case in a retractable sleve and hold it square before and sizing starts.

    76.2 gr H-1000
    0.010" into the lands at 3.590"
    CCI 250's
    Remington Brass

    Best group is a little less than 1/4 MOA but very consistently below 1/2 MOA at about 2935 fps.

    Been using a Lee Collet Die set with good luck. I have had four firings so far without having to push the shoulder back. No loose primer pockets yet either.

    Send me your e-mail via PM if you want and I can forward you Berger's load data they e-mailed me.

    Thanks.
