Like you I just loaded some test loads that were waaaaaaay over my intended max of 28,000 PSI, again the same as your max, and fired them remotely from a safe distance. No other testing is necessary and I don't see how a lab would offer any more assurance than the badly flattened primers and somewhat loosened primer pockets that resulted from my two heaviest test rounds, there were zero indications of any additional looseness in the action, no increased clearances or any other changes I could find. Besides pressure testing with controlled intentional overloads is the usual way new firearms are tested and has been since the invention of gunpowder!
