I’ve been reading some since you posted this. If you search, you’ll find others who also were getting measurements of a short throat, using the Hornady OAL Gauge. But when they went to reloading, they just loaded to normal, based on whatever loading manual, and all well with the world.

If your chamber is good, there isn’t really a way the throat can be short for the 6.5x55. The SAAMI throat length is super long! You might want to try loading a few dummy rounds to COAL you wish & chamber them. Let me ask, we’re you actually getting Lands marks on the bullets when testing COAL? Or was the bullet just stopping?
