    I would imaging the same powders that work well in the 7WSM and 7-300WSM. So RE-25, and H1000 would be a good place to start. H1000 should yield better barrel life and RE-25 a little higher velocities.

    I will be benefiting from your answers as well. I am developing loads for a 7 SAUM now.

    I/ve had outstanding accuracy with 57.5 grs. of 4831sc and the Berger 180 vld,the drawback's are velocity from 27.5 in. barrel is about 2800 fps and load density is not too good.

    H4831SC, RL-22, RL-25, H1000 all work in the 7mm WSM combos (270, 7mm, 300) as well as teh 7SAUM.

    RL17 will most likely get you the best velocity.

    I'm currently using 56.5 gr of RL17 with 168 gr Bergers. I'm getting 3050 fps out of a 28" barrel with no pressure signs. I plan on trying H1000 or H4831sc because of the temp stability.

    Are you finding RL17 to be temp sensitive?

    I haven't had a chance to shoot it in warm weather but I'm told that over about 80 degrees the RL powers will be hot. I'm looking for a powder that I can shoot prairie dogs in the summer and coyotes in the snow with the same drops.

    Alliant "claims" that RL17 is temp stable at higher temps. I've read conflicting user reports on it. I'll be experimenting this spring with my 25-06.
