    Berger 210 Grn in 300 rum sendero

    I could use a little advice. I am having fair success grouping Barns TTSX 180 bullets , but would like to try using the 210 Bergers . I cant seem to get them to group well at all. Does anyon have any load recomendations for 210 bergers in a 300rum sendero. Any OAL length recomendations also. I understand Berger Bullets are fussy that way.
    Thanks,
    Toklat

    read bergers recommendations about seat depth

    I think you will find that retumbo works well in the rum

    retumbo

    powder charges near max seem to work best. I actually had the best accuracy with the 175 Gr. Bergers, (4 inch group at 500 yds) the 210's are pretty close, but not as good.

    210 Bergers +.010" in the lands, RP Hulls, F215 Primers, 90 to 91.5 grains of RL-25. Skip the Retumbo. Watch for pressure signs and never exceed them.

    Your rifle is a 1-10 twist

    If your rifle isn't grouping well switch to the Berger 210 BT Match bullets as they are easier to get to shoot than the VLD's.
    On the VLD's try 0.015--0.020 into the lands or 0.120 off.Thats what my rifle likes the best.

    This what the Berger site is recommending for the VLD's. Your first attempts are with the bullet into the lands, with various charges. If none work, then back out with some bullet jump.

    FWIW, I am using 104.0 gr of US869, Fed 215, RP Brass, and Hornday 208 gr A-max. No pressure or case expansion.
