Taking Bill's explanation of the SAAMI spec reamer having plenty of clearance and that the tolerance is the toolmakers decision, along with "Dave's" explanation of the tool having too tight a tolerance, it seems to me that the chamber is too tight. Is this because the tooling is worn and not cutting/reaming as much material as it should or is the tolerance on the tool at or below the small side.
Throw in a little heat and carbon and things get sticky.
Send it to Bill and have his guys run their reamer through it.
