Within reason, proper placement of a properly constructed projectile usually trumps case capacity and bore diameter. The 0.020" difference in bore diameter between the 260 and 7mm-08 is, for a practical matter, inconsequential except in the mind of the shooter.
Distillation = no practical difference if the shooter does his/her part.
Or so it seems to me.

My regular using rifles are a .260 and a 7x57(same as 7mm-08)
Different guns but same terminal effects.
