Well have 2 6.5 Creedmoors, they are very accurate shooters, there are a lot of factory ammo options, so many I never really got into reloading it. Hmm, as far as the advantage over a 7mm, bought a 7mm PRC just to see if my daughter would prefer it. She likes shooting the Creedmoor. The 7mm PRC has a bit more recoil, than your 7mm-08. In hindsight maybe should have looked at a 7mm-08 or a 280-AI, instead. But shooting T-Rex's on the moon personally would prefer getting one of those Brontosaurus, and have a good Bronto burger or Ribs like the Flintstones. May have to move up to my 375 Ruger for that bad boy.
