Have you tried hand-tuning the extractor for proper tension?
At one time, Williams had online instructions for the novice. Thumbs are fulcrum, fingers/hands are lever. Middle bowed out, brings claw and tail inward, greater tension. Reverse, less tension.
I've only thrown away MIM units for steel, so not sure if that would be of issue. But, every good Mauser was fit with an extractor at some point, by hand. Even when NH Winchester dumped the old problematic MIM extractors, and switched to the Williams extractor, he had to give special instruction to their assembly employees, he may have even set them up with an idiot proof mandrel, because at first, they were tossing the extractors into the rifles with zero adjustments, and customers had complaints like yours.
