I typically do not remove the extractor to set headspace, but on my 7mm rem mag with the go gage I needed to. The gage would not snap past the extractor and since it is steel, It stated to mark up the extractor. I did not want to force it. This bolt face worked with a 300rum go gage fine with the extractor installed. The extractor was very easy to remove and replace and in the future, if I notice any issue, it will be quickly removed without hesitation.
