The Germans are more organized about this than we are. There is a central club there that tests handloads for shooters. They test first in a copper crusher, because that's harder to damage than a Piezo transducer. If the crusher result is within reason, then they test it in a Piezo transducer to get a number. Given that they use test barrels, obviously the idea is to see how their handloads compare to factory loads. I wouldn't be surprised if some of their clubs disallowed untested loads or loads that exceed CIP standards to be used around other shooters. It would also limit damage to indoor backstops.

Otherwise, the only reason to do that kind of testing, AFAIK, is if you are going to use the same load in multiple weapons. I don't think people there own multiple same-chambering weapons as often as we do, but it may give them a basis for sharing load information with others.
