I didn't mean to start a debate on the Remington extractor. In fact, all of my Remington's still have the factory extractors. I've only had two fail on me personally. One was a 721 that completely popped out (not while extracting) the other was a 788.
As far as polishing the raceways, I don't have time right now to go into all of the details, but simple use will slick them up pretty well. If you have a stainless steel reciever, you experience increased galling and no amount of polishing will make them as slick as chrome moly. I'll get back with the polishing procedure when I have a little more time.
