I've owned both, shot deer with both, and I still don't see any advantage of the 25 over the 27. The 25 burns too much powder for serious varmint use and the 270 with 100-130 grain pills covers the same ground at the 25-06. To me the bonus is heavier bullets in the 270 which make it a better bigger game hammer.
Of course I just picked up a Montana 270 which will become my mountain rifle.............
