Wonder if the twist was determined by mag constraints or simply that 1-9 is their standard in .243s too?
Anyway, the Creed version makes more sense unless you factor in nostalgia. Hell, why not a .250/3000?
Ruger advertises the ROT of the 6mm Creedmoor as being 1-7" and the 243 as being 1-9", so it seems that they could have gone either way without any extra effort.
A nostalgic cartridge chambered in a rifle that is anything but nostalgic seem out of sync to me.
