FIELD gauges are slightly shorter than the SAAMI maximum in order to give a small safety margin. Cross-compatibility: Many of our headspace gauges are compatible with multiple chamber specifications. For instance, .30-06 Springfield headspace gauges are usable in .25-06, .270 Winchester, 6.5-06, 8mm-06, .338-06, and .35 Whelen chambers.

It's an article with some history (the first Piezo gun pressure measuring device was made in 1922; the copper crusher was invented in 1860) and it presents data on a copper crusher vs. a non-conformal type Piezo transducer (gas sampling) that is co-installed on the same .30-06 barrel. The tests are done by H.P. White Laboratories.
In the early 1920s, SAAMSA ceased to exist and the idea was not revived until 1926, at the urging of the Commerce Department. SAAMI was initially created to cut the number of obsolete black powder rifle and shotgun shell loads, which it did. The industry team reduced the number of metallic cartridge loads by 70 percent and shotgun shell …

When the crusher method was first devised, bullets measuring .355~.357 (9mm to 38 cal) were used to set the standards because they were about average size so CUP was very close to actual psi. Pressure was thought to …
At SAAMI they run from 11 ksi for the 10 ga to 12.5 ksi for the .410 in the standard case lengths, but a few of the longest shotshells are as high as 14 ksi. References.

By this time, SAAMI had also adopted a new method of pressure testing, which would change the way that .38 Special +P pressures were measured and expressed. With the development of the electronic transducer, a new method for measuring pressure was adopted by SAAMI, in preference to the copper crusher method.
