Brit,
Yeah, Ive thought about it. Ive always kinda had a love affair with the 25-06. Its not much more than the 257, but a bit. We all have our preferences....
I have considered the 6.5x55 seriously. I have been exposed to them quite a bit and they are impressive. I agree stongly with that. After I wrote what I wrote above, I actually thought about that. I have a 25-06 and that 6.5 might be a nice addition.
Ive studied alot of cartridges I hadnt studied much before this thread. I have killed a deer with my buddies 280 Mountain Rifle once when I had some technical trouble with mine. It was very impressive and after studying ballistics on it closer, thats a real option. Awesome ballistics, velocity, trajectory, enery, bc, its got it all.
Decisions, decisons.

I would bet that since I already have the 25, I will end up with either the 6.5x55 or 280.
I really do need some more deer rifles.
