Well I've got an Accumark here that say's they have before. How do you think I know what the extractor costs?
Its more common with Remingtons and their C-clip extractor.
Other things you can check are dirt, metal or burrs under the back of the extractor, or interference on the drift pin or in the groove. The spring could have also been changed to a heavier one.
Or maybe you are imagining the whole thing, cause Weatherby wouldn't do that.
