    I do not have any info on the 7MM WSM load data for the guide but I have recently dealt with Parish Davis in Mobile Alabama on a Feinwekbau 300 s . He owns and operates a business there "Extreme Rifles.com"
    is His business. Via our mutual introductions and acquaintances the talk led to gunsmithing and our favorite cartridges. I shoot benchrest and he shoots / is into longer ranges. Bottom line for Him is the 7MM WSM bar none.
    He is a member here and has valuable load data for the 7 MM WSM.

    Anybody try rl-26 or 33 in their 7-270wsm or 7-300wsm?

    It appears H1000 and rl-25 at 65 gr produce same velocities, so wonder what the new 26 would produce

    7 WSM
    175 ELD-X
    65.0 grains Reloder 26
    Federal 215 M
    .130 jump (my gun hates these bullets any closer to the lands for some reason, but .040 works in most guns)
    2,950 fps in my 26” Proof Research Sendero Light
    1/2 to 3/4 MOA at 100 (not great)....but...
    1/2 to 1/4 MOA out to 1,085 yards
    This is the first instance where I’ve actually seen a bullet get more accurate the further you shoot it!

    300 WSM
    Federal Brass 68.5 Reloder 26
    Norma Brass 66.3 Reloder 26
    215 Berger Hybrid
    COAL 3.01” in Winchester Short Action
    2830 with Federal Brass
    2805 with Norma Brass
    CCI 250 Primers

    300 WSM
    Federal Brass
    200 ELD-X
    2.95” or so
    68.6 Reloder 26
    2934 FP*Lowest ES was with Winchester LRP
    I ran this “cheap” “junk” Federal brass for 8-10 firings without annealing when I was first starting out. I finally pitched it after I could seat the primers with my thumb... but it still shot great.

    Bertram makes good brass but it still needs weight sorted. Norma brass has been pretty unimpressive-needs full prep and is softer.

    If you can’t run Lapua, Peterson, or ADG, in mummy opinion just buy a bunch of Federal or Winchester. Fully prep and weight sort, and anneal if you can. I’ve gotten the best velocity and as good or better ES with it!
