Nothing wrong with a short action 338-06 +P. I am kind-of interested myself.
My guess is that feeding would be smoother than the WSM.
Per the reviews, in factory loaded form, it gives up nothing to the 338WM (though I am sure it does with heaviest bullets).
Hand-loads are likely to be a different proposition, with performance more like a 338-06 +P, since the propellants used in the factory ammo aren't available to the handloader.
