If the extractor springs are weakening (even more) after heating up that could definitely be your problem. However, your testing method of swapping the entire extractor introduces an entirely different problem of having an extractor that isn't tuned for the proper cartridge.
Put the original extractor in with a new spring/o-ring and test again to rule out low extractor tension as your issue. Also, removing the o-ring would only exacerbate this particular issue
.
I will definitely give this a shot. At this point I am willing to try almost anything.
