If you use the generic gauge, you may not actually measure the contact point that creates headspace. I am sure you have reamed barrels. I am sure you know the amount of error in most reamers. My point is you are measuring a spot that might not be "the spot". In a perfect world, the generic gauge works. In real world, it may or may not be accurate.
