Have Federal 6.5 CM cases some marked FC 6.5 Creedmoor and some the same but in bolder type.
The bolder type version has a larger case head diameter which required a different adjustment to Co-Ax primer system and noticeably smaller case capacity.
The plain FC case is almost exactly the same case capacity as Hornady brass. The bolder type version is smaller.
I believe the bold version had blue primer sealant.
Be careful out there.
