Been hunting with the 260 Rem since it hit the market in 1997. Own a Model Seven with 20" barrel and an A-Bolt with 22" barrel. Only hunted Whitetails but never lost one. Longest shot was 300 yards but most inside 100. Don't have any idea how it would be on Elk but if I were after Elk I would carry my 300WSM. My son hunts hunts with the 7mm-08 and is quiet confident with it. All that being said if I was buying today I would probably go with the 7-08 over the Creedmore due to ammo availability.
