Also be aware that wads can change the pressure profile.
I always used the win aaa trap wads becuase they were available, cheap, and worked fine with all my loads of unique.
With shortages i grabbed a bag of whatever was available, and found that some were “tighter” than the aaa,
So set them aside for later or cut off the petals to use as “wad only” like using a cork wad. Usually but not always, reducing the shot
Or powder can get you into safe pressures, but one REALLY wants to research carefully from the shotgun forums where those guys
Send loads off to be pressure tested. Shotguns can “pop” too easily and i still like my face.
Or worse case, use old timey wads and BP.
