I've had no problems with the extractor, however small amounts of brass were being shaved by the end of the ejector. This, in my 700, was causing the ejector to become jammed in the depressed possition. The fix was to remove the ejector plunger and polish the end until it was slightly dome shaped and almost mirror smooth. Also as I recall the bolt face at the ejector hole had a small burr or two, so a VERY light chamfer was necessary to clean this up.
To date I've had no more trouble with the ejector and find very few brass shavings on the bolt face after a day at the range. Where as before I was lucky to fire 3 rounds before the ejector became jammed due to the bits of brass getting in where they don't need to be.
If everyone thought like me, I'd be a damn fool to think any different!
