The 6.5 Creedmoor is the fad. Ken Waters took the .243 Win and opened it up to what he called the .263 Express. in 1956. He commented in 1984 he wished he had used the now (and then) more popular .264" bullets. The neck diameter is the only difference vs the .260 Rem. And the 6.5-08 wildcat had a following before it went factory.
A 6.5X55mm Swede with a higher allowable chamber pressure that fits in a short action. What's not to love?
