[QUOTE="Hand Skills, post: 1496747, member: 103303"] Thank you for the detailed response, that is exactly the kind of info I was looking for. I added some tension to the extractor - carefully inducing a set of about 5deg behind the collar. It was more difficult to reassemble with proper tension - I was careful with alignment and now the rifle extracts and ejects reliably. Still, the bolt throw is not glassy smooth. I'm now confident the extractor ring has been deformed and is not holding the extractor as close to the bolt body as it should. That or the raceway has been worn - there is some nasty scaring under the extractor ring. Either way, the extractor is not riding as tight to the bolt as it should. This is evidenced by contact with the receiver. Ordered a factory replacement extractor ring, will post some photos of final assembly. Might see if I can obtain the factory spec for the diameter of the raceway the collar sits in just to rule it out. [/QUOTE]
