I had understood that if you replace the Rem 700 extractor you also need to drill holes in the bottom of the bolt body to vent gases down through the magazine (and away from your face) in the event of a primer or case rupture. As shown in examples given, if all you do is install a Sako extractor there is no place for the gas to go and the action was never designed to handle gas that way.

Remington do install a Sako or M16 type extractor on their M700 in 338 Lapua but I can't recall what else they did to the bolt to handle the venting of gases in the event of a failure. Maybe someone that has one could comment?
