Extractor issue

[Crusty]

My Alexander bolt (designed by the guy who invented the caliber) has an o-ring on the extractor so I assume that Bill thinks it's needed. Don't go overboard with extractor force though - too much extractor force shaves brass off your cases and leaves the shavings on the bolt face to cause other problems. The main thing is that the extractor points need to be rounded and smoothed until cases come off of it easily. If you still have problems after that, an enhanced ejector spring will usually flick them off the bolt nicely.

BTW, did you happen to notice that those two marks on your cases are the same distance apart as the points on the extractor? I've seen a fair amount of range brass with grabby extractor marks so this isn't an uncommon Grendel problem.
