IT is my shop policy to fit every Rem 700 receiver I accurize with a Sako extractor before it leaves the shop. When fitted correctly they are vastly superior to the factory extractor in every way.
As far as an extractor coming out of the rifle, sure, its possible, but I have yet to see it happen personally and I have installed more then 300 of them over the last 5 years.
With the right fixtures and a quality mill, its a 20 minute job and very worth the benefits.
The way the Rem 700 is designed, there is no way an extractor that comes out of the rifle couldhit the shooter other then possibly in the trigger arm elbow, other then that no way it could get to the shooters face or eye from what I see unless there is serious receiver failure. In that case, even the factory extractor would probably hit you in the face.
If that is a concern of yours or you are left handed shooting a right hand Rem 700 with this type of extractor then I recommend a pinned in extractor such as the Badger Ord extractor which simply can not be blown out of the bolt.
There have been alot of wives tales spun about Sako extractor horror stories, for the most part they are started by smiths or so called smiths that do not know how to properly fit one or will not invest in the tooling to do this properly.
