The 6.5 Creedmoor's faster flatter little sibling built by necking the case down for shooters chasing less recoil and less wind drift on the target line. It arrived around 2017 and the competition crowd embraced it fast because in a discipline measured in fractions every advantage counts. Barrels burn quicker but the scores speak for themselves.
Loads run 90 to 108 grain heavily weighted toward match. A precision caliber that prices like one in 20 round boxes. Production has grown steadily so the patient shopper finds better numbers than the early days offered.
