    7mm Saum load with 180eldm rl26

    Has anyone got a good load with 180eldm or berger 180 and rl26.
    Seating depth not an issue
    Twist rate; 1:8.7 (maybe not fast enough)
    Thanks Garrett

    Should be heaps of twist. I shoot both of them through factory tikka 7mm mag barrels. Can't help on the saum front though

    Greetings GKP,
    Hornady recommends a minimum twist of 1 in 8" for that ELDM. Stability would be marginal at best. A check at long range would check.

    I run them in a 7mm08ai tikka 9.5 twist @2650fps. No issues with stability so your 8.7 twist should be fine

    Nice! That's sounds like a sweet load for a non Magnum short action

    Close but not quite. Ive run 180 eldms and re26 in my 284. Stabilised just fine in a 9.25 or 9.5 (cant recall but its one of the two) and going slower than they will from a Saum.

    I do run re26 in my 7Saum too but with 162s. Havnt tried the 180 eldm in the Saum as yet but plan too.

    Cheers @GWH
    My interwebbing leads me to believe that 60g of rl26 with the 180 is the sweet spot

    LA bolt stop and mag. Barrel was reamed for 175 SMK's seated long so plenty of room for powder.

    I presume it’s a Bartlein barrel with 8.7 twist? I have one on my 7RM and load 180s and RE26 for 2840 fps from a 25” barrel. The twist rate is more than enough for 180s at those sorts of speeds.

    Try flicking Cam @camo wsm a message. I'm sure that he will have tried this combo

    If it's not a first round hit you need to practice more

    Should be fine with that twist mate. I have seen on the Web that 60 grains of rl26 is the sweet spot, so work up.
    Still waiting for mine to arrive but will post any findings. Let us know how you get on.
