Question: 6mm creedmoor is what caliber?
Answer: The 6mm Creedmoor is a necked-down version of the 6.5mm Creedmoor using 6 mm (.243 inch) bullets, lighter than 6.5 mm bullets with similarly-reduced recoil. John Snow at Outdoor Life designed it in 2009. As of May 2018, Savage Arms offers three bolt action rifles and one semiautomatic rifle chambered in 6mm Creedmoor.
