I have killed lots of deer with both the .308, and the .260. I really liked the performance of both. My .260 does real well with Hornady 129 Interlocks at 3010 fps. That being said, for your ranges, I would take the Creed, if I was bent on getting a new rifle. It handles the long bullets a bit better, due to its design and gets nearly the same velocity as the .260.
Bottom line is that they will all do the job,
