I have a 6.5 CM. Can see no reason to switch from a 7/08 or .260, unless the rifle has other aspects you need. A reason the 6.5 CM might be doing so well is a growing wave of older farts learning that they don't need to get kicked hard or carry a heavy rifle to kill things and perform well on targets. Another reason is the modern tendency to twist rifles faster in order to maximize BCs, since everyone buys a rifle based on spreadsheets. It does deliver excellent return per unit of recoil invested. And there is some very good, cheap loaded ammo out there for it.
I do not entertain hypotheticals. The world itself is vexing enough. -- Col. Stonehill
