I think your choice is fine, only thing is I would have went 1-8" twist, But unless you are shooting 130to 140 gr vlds or hybrids , they "may " not stabilize. Of the 6.5 cartridges in the group of a bunch , I think the .260 is the best , easy to form brass from others in these hard times faster then a 6.5x47 without way high pressures and still fits in a short action, 6.5-284 and 6.5x55 will not. The Creedmore is sort of the same as a .260 just a little different. I think the Creedmore and a
.260 are equals and I built a .260 because I had brass and dies offered to me for free, And I still love mine.........
