    I have a Remington Sendero in 7mm RUM, can not get 180 grain Bergers to shoot. I was told the twist rate is 9 1/4 and needs to be no more than 9.
    Anyone have any luck shooting these bullets with a factory Remington rifle.

    I shoot 180 bergers with a 7mm WSM it has a 1 in 9 twist and at 3000 fps they fly perfect so I don't know

    Your Sendero has a 1 in 9.5" not 9.25", some people at higher elevations and lower pressure ( thin air ) have no issues shooting them. MV is also a big factor, if you can push them faster they may stabilize.

    if they are not keyholeing they are stable. the long bullets with little bearing surface are finicky and need really good barrels, factory barrels are usually just ok . maybe adjust seating depth or powder.
