Reading several posts about the inaccuracy of the 25-06 and how hard it is to dial in, and while that maybe true for some and some rifles, I have not experienced this. Actually, some of my very first factory rifles were very accurate, sub 1/2 moa, and the custom barrels are even more so. I have an older, 1990's, 26" medium varmint barrel 25-06 that still prints 1/3 moa groups with NBT's, and that rifle gave me my first 1,000+yd P-dog kill shot. Also, with 26" tubes and Retumbo, I am pushing the 110's just over 3.300fps, so the 25-06 or 25-06AI can be made to shoot well and fairly hard.
That said, a good 257W will usually ballistically outperform the venerable 25-06, but at a higher cost and less ease of locating or making brass. Personally, and after so many decades of usage and success, I am biased toward my old friends in 25-06. YMMV
