In my rifles, I measure the depth of the chamber to the start of the rifling with a hornady gauge and modified case. I found that in two of my .308s, the ideal length of bullet seating for the chamber is actually too long for my magazine to accept.
.260 Remington, being based on a .308 case, could see the same problem. The case takes up a lot of magazine length, leaving less room for bullet seating.
6.5 Creedmoor cases are slightly shorter, but because of shoulder angle have similar volume. This allows me to seat a long heavy bullet further out, so that I can get the ogive of the bullet close to the lands of the rifling.
It's an advantage if you're reloading.
The whole 6.5CM basis was an off the shelf budget target rifle with off the shelf affordable factory target ammo for non-reloaders. In that regard it was a success.One of the advantages of the Creedmoor over the Swede and the 260, is a much better selection of factory TARGET ammo due to its popularity.

In the real world it's a 260Rem that holds 1gr less powder, and you can still get better results reloading.
For now, anyways.
While I'm not into fad guns much, this is one advantage the 6.5 does offer over other cartridges esp in short actions. I'm tired of factory chambers/throats that need bullets seated out too far for the magazine or even get a proper bullet hold from the case neck.6.5 Creedmoor cases are slightly shorter, but because of shoulder angle have similar volume.
