The Remington CDL SF .257 Wby gets my vote. The 26" barrel will be better for a more complete burn with a cartridge of that capacity, as well. Plus, even if you only gain 50 fps over the 24", that's still a free 50 fps, right?
I had a Weatherby MK 5 Accumark ($2,200 rifle) in .257 Wby that the barrel started caving in around 75 rounds... It started life around a 3/4-1" shooter, then once the barrel started caving, it went to a 1.5", and then around 150-200 rounds down the barrel (at the end of the time I owned it) it was a solid 2"-2.5" gun at 100 yards.
I don't trust any factory Weatherby barrel after that, no matter how expensive the rifle is. I would rather put my faith in a random used no-name pawn shop rifle that looks like was found at the bottom of a swamp, than risk buying another factory Weatherby.
I've had cheap factory Remingtons that would shoot lights-out, and I've had a very expensive top-tier factory Weatherby that wouldn't... So, when it comes to factory barrels, they're all a crap-shoot.
Just my personal experiences.
I also agree with Frank. The .25-06 will do ****-near everything the .257 Wby will, but will cost you 1/3 of the price. I have a custom .25-06 AI, and I have shot and compared it side-by-side when I still had my .257 Wby. And it is within 100 fps of my old .257 Wby using the same powder and bullets. And brass costs me virtually nothing (comparatively), barrel life is better, ammo is cheaper, it uses less powder, and the case is more efficient, recoil is significantly less, and muzzle blast is significantly smaller.
If you have not looked into it, I would look into a new Remington 700 Long Range in .25-06. For the money, it appears to be about the best bang for your buck.
