There have been several threads on this website in the past year comparing (or bickering) about the 6.5 creedmoor vs the 260 Remington. The two are very similar. Both use 0.264 projectile, both fit in short action weapons, both have very similar velocity. For Me, the 260 would be the choice. But there are advantages to both rounds. Read the old threads before you make up your mind.
