Fifth, I'm surprised at you. Really a 270??
I know, I know. What I really want is a 6.5-06 but finding that in a factory rifle is near impossible. I suppose the 264 WM is an option but I've got enough magnum barrel burners at the moment and think the 6.5-06 would fill a nice hole in my rifle stable. The 35 Whelen is arguably the harder one to justify, as if a gun purchase can be "justified"......looney. Anyway, I do have a hole between my 300 WSM and 375 Ruger but the logical choice is a 338WM. But who ever said a rifle looney is logical? The 35 Whelen has good style points in my book so it is getting some serious consideration.
