Yes, hard to give a good answer without knowing just what it is that you have. Serial and stock style as Calhoun requested also the brl address so we can tell when it was made.
One characteristic of the early Savage 250 brl is that it has a 1 in 14 twist vs the later standard 1 in 10. The early brls have problems stabilizing 100 grain bullets unless they are very short in length. The brl was designed to shoot an 87 grain bullet which that round is no longer loaded.
I would advise putting the same weight brl as you currently have or you will have to fit a new forearm. If you want an octagon brl and have a round you might be wiser to buy a different rifle and sell what you have.
