I do have a rudimentary understanding of the function of CRF and push feed rifles and I still maintain that a properly functioning example of either will work just fine in the field. In truth, the person who would screw up with a push feed would probably find a way to screw up with the crf rifle as well.
I liked the scenario where the shooter partially extracts the case then tries to put it back in. This would be important in those cases where the shooter wants to pull the trigger on it again just to verify the loud noise and recoil was indeed caused by the round going off! If a person experiences this kind of malfunction more than once it's pretty important for the problem to be addressed. The best way is to go to the range with a buddy. The buddy's job is to slap the shooter in the back of the head each time he does something stupid. Like pulling a fired case halfway out then trying to put it back in.
The statement about almost short stroking the lever action was also interesting for a couple of reasons. First; How do you know when you "almost" short stroke something? Second; Did you know that most lever actions are push feeds? The Marlin 336 comes close to being a crf but not really. You shouldn't even be using one of those things.
As I said before; one real advantage to those long claw extractors is that they can be changed easily in the unlikely event of a failure. If your Remington 700 extractor screws up, you're going to need some tools. The newr, non-riveted type are better in this regard but still not that easy. Regards, Bill.
