Im pretty sure Hornady is the only one who makes factory 6.5 creedmoor ammo and you can only get it in their "Superformance" and "Match" lines
Ive never fired a round of 6.5 creedmoor but everyone Ive heard of who has a Savage chambered for it are very pleased.
Savage and Hornady are closely linked anyway so it makes sense that they would design their rifles with Hornady ammo in mind.
You could always ditch the 6.5 creedmoor idea and get a .260 remington
