Not exactly. The creedmoor and .260 are ballistic equals. The Creedmoor is a little shorter and will allow longer bullets seated closer to the lands without invading the powder column. Both can be used effectively in a short action. The Creedmoor has a little advantage in being able to get accurate factory ammo.
As always it’s up to the individual to choose what he wants.
Cheers.
That's not the reason for the shorter Creedmoor case. It is shorter so the ogives of long nosed vld type bullets stay forward of the case mouth when the overall length of the cartridge fits a 2.8" short action magazine.
