John : I assume that you are referring to the OP's original question.
In typical 24HrCF fashion, we have long since meandered into only semi-related territory.
Honouring
Bob in NH's memory, and our friendship with him through this medium. It's all good.
I didn't know him as well as some of you, but I benefited greatly from our exchanges, and I've missed him, Lots.
As for the two big 6.5's The Nosler is very interesting, but the .Wby has the long neck, and the long magnum magazine.
Much like the 6.5 CM, the Nosler 26 is built around magazine, and specific action constraints of the N48 / Howa derived action.
Ultimately, No it doesn't matter. I think the Wby wins on the basis of the Mark V platform, and the Weatherby mystique .
Carry On
