    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
