    My pet load is 92.0 gr of retumbo OAL 3.910, bout 2805 fps with 300 gr Bergers that is out of a 28" Douglas the barrel is new I am hoping it will get faster with a little breakin.
    Seeing how Retumbo is unavalible at the moment I will be trying VV n570 I may have some load data soon.

    Maybe jut my lot of H-1000 but 88.0 300 gr otm fed gm215 worked rem cases right at 2700 ish. I went height and groups opened up. Going to try retumbo, when the weather get better. My only consern, would be compressed to much. I am shooting form the mag Wyatt ext box. Keep you posted..
