Actually the .257 WSM is NOT the same performance as the 25-06. It is much closer to that of the .257 WBY Mag. To answer the original question, I hope they will dump the POS 25 WSSM and do the 25 WSM. A .264 or 6.5 WSM is just to close to the .270 WSM. I mean really, what you going to gain in a whopping .006 less diameter of a bullet?
