One more pitch,
I just checked eBay and saw at least a half dozen Remington 700 .308 takeoff barrels, most at less than $100 at this point. That's another option you might consider. You can put one of those on, play with it as long as you like, and still retain the option to put it back as it is now. The Lyman Alaskan will more than pay for the M700 .308 barrel. A couple of them are long heavy varmint contours meaning you could turn them down to about whatever contour you want, even to match the current barrel so the stock stays a perfect fit.
Good luck with it. How about posting some pics of it once you get it home?
