I like this hypothesis.I think what happened here is that the grain size of the gunpowder got smaller and smaller as the round got handled and bumped around over the years,
and basically turned from slow burning big grain rifle powder into instantly burning gunpowder "dust". That would explain the enormous pressure spike.
Think loading a big rifle round with fast burning pistol powder. Same amount of powder as before, but now you get an insane pressure spike because the whole charge goes off at once instead of "slowly" burning as the round travels down the barrel.
Powder grinds its self down over time and the fine particles eventually find their way to the same spot like oil floating on water. Could probably diagnose this visually by opening up a cartridge.
Regardless the powder should be sent to a lab that can verify its composition.
