6.5 Creedmoor is a good long distance round. Kicks about the same as a .243, but is still a 1000 yard cartridge.
I realize it’s not used by the military, but just sayin’.
SOCOM and DHS have adopted the 6.5 Creedmoor for some applications. I’d look for its use to expand. The shelves were heavy with it, locally, after the common military rounds disappeared in the current ammo drought.
