I'd go with the short action for weight savings. Caliber-wise, I would be concerned about the length of the magazine box in a short action and whether it would let the cartridge take full advantage of the long 6.5 (260) bullets without having to seat them too deeply and compromise powder capacity. I probably would go with the 7mm-08, although my personal lightweight rifle is a .308 that probably recoils more than the 7mm-08.
