If only building one rifle, I'd split the difference and do a good magnum-sporter weight rig in a SA 6.5mm chambering, like the Creed or the 260. With a 22"-23" #3 or #4, it wouldn't be too terribly heavy and would be enjoyable at the range. Like others have said, build for balance. A standard-fill stock would work better here than an Edge. A 22" #3 contour Creed in a McMillan Hunter would be hard not to like, and good factory target/hunting loads abound, should someone get in a position to not handload.
