    Recommend powder for 7mag. I tried rl23 and it sucked. 162 grain soft points is what I’m shooting. Also it has to be temp stable.

    H1000 or Retumbo are my first choices for 7mag. H4831 will shoot good but I've never been able to get very good velocities with it before hitting pressure.

    Definitely H1000 and Retumbo are go too powders for the 7RM. H4831sc brings excellent accuracy but lacks velocity.

    Please explain your reasoning as to why RL23 "sucked".
    I've gotten good velocities & excellent accuracy with RL23 & everything from 139gr SST, 140gr BT, 140gr GK, 150gr BT, 150gr ABLR, 150gr ELDX, 154gr SST, 160gr GK, 162gr SST & ELDX, 168gr Berger VLD-H.

    Oh, and it's "temp stable".

    RL 25 70.0grains and Nosler 160 accubonds are great in mine

    Rel 22 and Norma 160.

    For me using 154 gr. bullets, they are both giving me the best velocity, accuracy and pressure I have found.

    For velocity, RL26 is the King. For temp stability, there is none better than H1000, it'll just be about 100fps slower.

    I shoot a 7mm Blaser mag, ballistically, it's a near twin to the Rem 7mm mag. I shoot the 180gr Bergers 3100 with RL26 from a 26in barrel. Never shot anything as light as a 162 but my guess is it would be in the 3250 range with RL26.

    My groups were garbage with rl23. Nothing under 2” from the 50 rounds so far. Speed was around 2850. I was hoping to get it to work as I have that powder. It’s impossible to get any of the above mentioned. Rl 22 and 25 are stable in temperatures. I won’t use them.

    I shoot two 7mm Mags. Both are great shooters.
    1- shoots 160 accubonds and H1000 or 162 SST.
    2- shoots 162 Amax and Retumbo.

    I don't know how available it is but if you could find some Viht N560 or N565 they'd work well too and they're pretty temp stable powders.
