    I would appreciate any load data for the 300 RUM using the 200 grain Nosler Accubond. I will be using Nosler brass and Federal 215 primers. I have plenty of Retumbo powder on hand and some H -1000 that I hope to use.
    The gun is a Remington Sendero with a custom 28" Douglas barrel.
    Thanks.

    Just did a ladder test with Retumbo at 92gr showed a good group.....
    Still plan on finishing the refining at each side of this load.....

    I prefer a full case (98 to 100% case density) and the RUM will hold 100+grains of powder
    so I would start using H 50BMG.

    Retumbo will get you a little more velocity but sometimes reaches max pressure quickly
    and below 95% case density.

    The big RUM has free bore (Most of the new high pressure cartriges do) but don't worry about
    it because the Accubond does well without touching the lands.

    Us 869 would be another one to try.
