I think the 6.5 WSM is a good choice for what you want.
That's probably Neal Cooper. His 6.5 WSM stretch (I can't remember exactly what he calls it) Striker has over 1000 rounds through it.
I've been considering a 6.5/375 Ruger, and I've seen a 6.5/338 RUM (I think he called it the 6.5 Badger). Either one would benefit from having the nitride/melonite treatment. The Ruger case would be pretty close in capacity to the 6.5 STW, and probably the upper limit of what you can realistically use in the 6.5 bore.
