I'm working on reloading 6.5 Creedmoor. After looking at saami specs and hornady book... Numbers don't seem to match up.
All my factory ammo when using the hornady compactor headspace tool seems to measure the headspace using the .400 D gauge at 1.531 - 1.533 - knowing Saami isn't that.. I'm guessing the gauge is more of a reference vs an exact measurement?! Just making sure I'm not going insane or something is off.. My calipers are zeroed with with the comparator on. Any info or encouragement is much appreciated!
