Test Validity Question

I had a (nother) strange thought this morning. It is my opinion that I have figured out how to do inexpensive compensating nozzles. I don’t have an engine to test the idea. Has anyone ever seen any nozzle testing that used a blank pistol cartridge? My thought is that I could turn a nozzle and firing chamber with pressure gauge for a 22 blank and record the results with a high speed camera. If the exhaust behaves as I predict at high to low pressures, then it might  be worth discussing with an engine builder to test on a thrust chamber.

Has anyone heard of such a thing?

Would the results be valid enough to convince real rocket men?

Do any of the real players need a compensating nozzle enough to spend money building one even if it is a valid test concept and is successful?

I do construction for a living and aerospace as an occasional hobby. I am an inventor and a bit of an entrepreneur. I've been self employed since the 1980s and working in concrete since the 1970s. When I grow up, I want to work with rockets and spacecraft. I did a stupid rocket trick a few decades back and decided not to try another hot fire without adult supervision. Haven't located much of that as we are all big kids when working with our passions.
