My decision to build a 6.5-06AI instead of a standard 6.5-06 seems wiser all the time. Thank the Lord I didn't saddle myself with a custom rifle using an obsolete cartridge!
Why build a 6.5-06 when a .260 Rem has it all over the 6.5-06 in terms of case design, efficiency, powder choice, etc? What would my girls have thought of me? The shame!!! The horror!!!
Why QuickLOAD , selecting just the .260 Rem, 140g AMAX and Hodgdon H100V powder, suggests a maximum velocity of 3,411fps . That puts even my 6.5-06AI to shame as it can only reach a chrono'd 3075fps with that bullet and powder! Making only one change, to select the 6.5-06 A-Square, the maximum QuickLOAD velocity drops to 2955fps.
I guess Lame_Bob is right - the smaller case dominates.
Either that, or QuickLOAD results need to be taken as less than gospel, as the manufacturer clearly states.

No, I'm not a Ruger bigot - just an unabashed fan of their revolvers, M77's and #1's.
