Not sure of the necessity with a 270 Win, 270 WSM and 270 Wby. A 270 Win w/1:10 twist will shoot the160 gr Partition or 150 A-Frame just fine at elk and moose out to 400-500 yards. If twist bugs you you could simply rebarrel to a fast twist 270 Win LA and get the most out of powder and bullet combo. That 270 Win would easily run with the 6.8 Western using less powder and a handier barrel length for alpine work.
