6.5 Creedmoor. I was between 280 AI, Creedmoor, and .308 but came across a really good deal on a Creedmoor and jumped on it. Likely a little underpowered for what I'm looking to do but I think it will get the job done.
Have you shot your rifle yet? How does the stock feel. I'm on the verge of buying one of these. Haven't made it to a store to check one out in my hands yet though.
