CRF certainly isn't essential, but my only failures to extract have been twice on 700s and twice on a Nula. Each time brass shavings from shooting had collected under the extractor and caused the problem. I've shot many more rounds out of CRF rifles than I probably ever will out of 700 variants.
Keep them clean and it's no big deal. Don't and CRF seems to be the winner.
