Thanks for reaching out Wendell! If your rifle is chambered for 6mm Remington, then it cannot fire 6mm Creedmoor. (The 6mm Creedmoor is just a necked down variant of the 6.5mm Creedmoor.) I regret that we haven't got any 6mm Rem ammo in stock for your right now, but we do update our inventory frequently. I hope you'll check back in again soon!
