I think that would have been counter productive to one design goal of the Creedmoor which was to allow for long ogive VLD style bullets to be seated so they fit in a 2.8" magazine without their ogives getting down into the case mouth.
No, the long bullet could still be seated the same and short bullets could be seated out near the lands (which is probably not that important either). Like I said, I just like longer necks. GD
