Building a 6.5 Creedmoor or a 260 (or even the x57 cartridges) on a Mauser action (or similar length actions) and the advantage of the Creedmoor design lessens, again in my opinion.
(I own a few 722 and short action 700's BTW)
Or, have our gunsmith cut a thread off and rechamber with a short throat. Lots less expensive than building another rifle.
