Figures plugged, using 10mph wind for arguments sake (yes, I realise neither of those will be the best possible round for each, just wanted to use the equivalent common hunting rounds).

At 400yds that 7-08 has 0.3" less drop and 1.8" less drift (and slightly less energy)
At 600yds that 7-08 has 2.5" less drop and 4.8" less drift (and slightly more energy)

So the 7-08 is ballistically better as you said, but I can't see the night and day difference people seem to suggest. Or is this like a Ford/Holden thing around here? (yeah I'm kinda new here)
