    Definitely put some powder in the case behind the bullet. Primers help to.



    ...so does load development.

    Google it. Assuming the 7LRM is yet another variant of the 375RCM type case then you’d be better off starting with a much slower powder. ADI2225 or RL26 or 33

    Thanks mate, I’ve done plenty of searching but most of the load data is for H1000. I’ll join that forum and ask cheers.

    I am interested to know if the twist rate is sufficient. Usually at 7RM velocities it would be too slow for 180ELDM, but given the added velocity it just might be ok.

    @ChrisW I run the 180eldm in my 7mm08ai with standard 9.5 twist Tikka barrel at 2650 and they stabilize fine

    Just a follow up, ran a ladder today with 2217 and .015” off the lands. Accuracy node at 70.5gr and 71gr with no pressure signs (in my rifle) Will need to chrono and fine tune at a later date, but for now it’s decent combo
