I have a Defiance Deviant SA with Mauser style claw extractor. Why? I just like CRF for hunting and I wanted a SA with CRF. Why not sure. I don't even like SA, LOL. The only benefit I really see is if you happen to not close the bolt fully on PF and the round stays in the chamber or partially in. Then you try to feed another one in. Jam. Short-stroking the action is also less of a problem on a CRF. Then again short stroking a PF will probably eject the empty anyway before you load another one or you will not be able to close on an empty case, realizing the problem. So, I do not see that as an issue unless you are trying to eject a round that failed to fire and has the bullet still in it and you short stroke, not ejecting it, yet grab another one from the mag/follower. The PF may jam. You can also jam a CRF depending on how hard or slow you work the action, etc., so I say get what you want and don't worry much. As long as you get used to how they work, you will be fine. Though I'd think even old 20th century (1908 model and up) Mausers and CZs are as strong as Rem 700, I do not have any data to support one over the other. Anything can fail.
I further believe the Mausers had extractors that snapped over the rim of the case. Can't imagine soldiers using Mauser not being able to single feed in a pinch. But anything is possible. The only rifles that did not pop over the rim was my buddy's Ruger Gun Scout rifle in .308. Mine did. His just did not have enough relief in the cut and the extractor was slightly bigger than mine in the claw shape and thickness. That added up. Then a Mauser or a Brno 21 I think but regardless of which, that one had few non original parts, so who knows where the extractor came from. Put a different bolt in it as a test and it snapped over.
CRF on a Mauser was nice as the C-ring in the receiver was used as torque shoulder against which the barrel was tightened and you could swap barrels easily. Also, less machining on the barrel. Just threads and flat surface at breech end. No cones, no relief cuts, etc. With systems like Defiance, Winchester, Kimber, etc. you have to always turn the barrel to the same spot exactly as it has a relief cut for the extractor as they tighten against the front of the receiver.
PFs are also generally slicker than CRFs, especially when tight tolerances are used. When trying not to disturb the rifle in a rest, that might matter.
