First, this thing about Sako blown back through the raceway to the shooter's face has been hammered to death. I agree with Mr. Taylor, you would have to blow the case apart to make it happen. But, how big was the barrel tenon to bolt gap? Under the circumstances a case blows and sends a Sako flying, do you really think that very small pin that holds a M16 extractor would keep it together? The cut in a bolt to install a M16 is huge compared to a Sako. I've never seen a "mini" M16 extractor, although I have heard of them.
Many of the finest benchrest actions sold use a Sako type extractor. This action was blown apart by a novice handloader, the action uses a Sako style extractor, the bolt and extractor was still intact.
