Those loads are indeed the listed loads for a 7mm Remington Magnum according to the Nosler Manual #6.
Nosler tested in a 24 inch Wiseman barrel. I would not expect much more in a 26 inch barrel. Only a chronograph will tell.
Nosler shows 63.5 grains RL 22 giving 3150 fps and 67.5 grains of RL 22 giving 3340 fps.
Those speeds sound a little optimistic to me, but that is probably due to the use of a test barrel and not an off the shelf rifle.
