That works great IF you know where your boltface datum is and you have a way to take accurate measurements on the barrel.
I made myself several specialized protrusion gauges that will reach around the barrel threads and touch the barrels shoulder and then measure how far a headspace gauge is protruding from the barrel shoulder.
There are commercially made tools like this now, but I made mine many many years ago before they were available off the shelf.
