I never knew the issue with the 17's. Sure been a lot of magnums built on that action. I do know of a heavy barreled Springfield (high number)that was bought by a friend of mine that was stamped .308 on the barrel. He fired a .308 in it only to find out it was actually chambered for .300 Win Mag. The extractor had held the case against the bolt enough to allow it to fire. No harm was done other than the case was split from stem to stern.
