I don't get on how the 6.5cm is superior to the '06 at long range
The 6.5 CM kicks a lot less. For most of us that translates into more, and more precise shooting. And a 6.5 CM can be built lighter, but still be comfortable to shoot. In the mountains that's a nice trait.
I'd also wager a 6.5mm/140 of equal construction to a .308/190 will equal (and perhaps exceed) the 190's penetration.
At the end of the day, a precisely placed shot with ample expansion and penetration trumps "energy" figures...
