I took Obermeyer's recommendation and bought a 1-8.75 twist barrel from him. It stabilizes the 142 grain bullets from Sierra/Nosler that I have used just fine in my 260 Remington. The barrel is about 27 inches long, and I get higher velocity than I expected from the round without any pressure signs, and while staying well below published maximum charges. I think I just got a fast barrel. In any case, Boots is right about that twist rate working...it does very well in my rifle.

It shoots great!
I'm a fan of Akley and his improved chambers. I however chose to go with a 6.5 Creedmoor instead of the .260 AI. The reason I did was because I didn't need the added powder space as I'm more concerned with recoil and barrel life as I use it for match work. And for hunting I have my 6.5 STW.

Is your Creedmoor a bolt gun or auto-loader?
