Every gun is different, but the 250 should be able to shoot the 55's well. Twist is only a part of the equation. Stability is achieved by RPM's. A 1-12 .223 is fine with 55's because the velocity is enough to get sufficient RPM's. The higher velocity from the 250 should give enough rotation for the same bullet in a slower twist rate barrel.
In life, strive to take the high road....It offers a better field of fire.
