    H 4831 is one of the best in the 7mm RM and the newer H4831SC should be better.

    Start in the middle of the loading manual and work up.

    I'm using Retumbo in my hunting partner's 7RM with fed 215's & 140 grn Barnes MRX. Just over 3200fps & good accuracy.

    mine just would not eat the 4350. I did find a good load using 62 grains RL22 with the 150 NBT.

    H4831sc or Hybrid 100v. I wouldn't use H1000 or Retumbo unless I was loading 160grn or heavier bullets.

    4831 or 1000 for the lighter to medium bullets
    R25, 2225, N570 for the heavier bullets
    Have fun :D

    I have enjoyed great accuracy with IMR4831, RL22 and awesome velocity and accuracy with IMR4350. I shot the 150gn NBT 98% of the time. JohnnyK.

    For hunting My gun likes 67.7 gr. IMR7828. Works great for me. 150 gr combined technologies silver tips produces sub moa groups at 100 yds. 2 hundreths of lands.
