Id do a plain old 6-06, 7.5 twist on a 1 or 2 contour. Inexpensive brass, ability to shoot about any bullet you want and no real detractors I can think of in the Kimber.
This^^^^^^^ or a 6.5-06 or 25-06. I just unloaded a stupid accurate Mark V accumark , 240 is too much of a tweaner cartridge for me and not unlike a 25-06.
