If you want to shoot longer, heavier, bullets in the 250-3000 you would probably be better off with the faster ROT. I can't see any downside in a 1-9" ROT, but the 25 WSSM, 25-284, and 25-06 will all launch 120 grain bullets over 3,000 fps with MOA accuracy from 1-10" ROT barrels, so either are likely to work fine.
