Can't imagine much I wouldn't do with a 25-06 and the 100 ballistic tip...
And I don't imagine the .257 would fall short either, despite my head quibbles on horsepower...
It won't, if loaded to it's potential.
My load posted above, 100 gr TTSX at 3266 fps over H-100V, is accurate and not over the line regarding pressure. That powder just works well in that round.
Now, looking at 25-06 Load Data, it's the rare 100 gr. load that blows that one away, most don't. Now, if one leaned on the larger round, displacement ultimately rules.
I would think the 25-06 would probably pull ahead with more authority, shooting heavier bullets.
It may not be too unlike the .308, '06 match up. Light bullets, not that much difference, heavier bullets the larger case rules.
