.257-300 WSM or .264-300 WSM?

[Gundigest]

Does anyone have one of these wildcats yet? How do you like them and would you do anything different?

Thanks

I believe winchester is coming out with a 25WSM so it may not be that far off, they should probably have done that instead of introducing the 25wssm . I understand from people that own them that they are very accurate and fall about 100 fps short of a 257 Weatherby.
