Oh, yeah, just call me Mr Rigby...

One more thing. My gunsmith told me it is common to remove that triangular portion of the lower claw when bevelling for snap-over. Why CZ would remove that portion but not go whole hog on every extractor to ensure snap-over is beyond me.

This whole issue has been a real eye-opener to me and I'm thinking it finalizes my feeling that the best overall action type I've ever used is the SAKO AIII/AV, with pushfeed and controlled ejection.

Having said that, certainly there are many Mausers that function 100% CRF, and there is nothing wrong with that! As a matter of fact, my son's FN .270 and 1903A3 Springfield are absolutely dead-reliable CRF, and I cannot get them to miss a shell loaded from the mag. Pointed straight down and jiggling the bolt back and forth and feeding slowly, an extreme test, nevertheless results in a totally controlled round as the shell pops up out of the mag and under the extractor every time.

This project has also exposed the importance of the magazine in Mauser CRF, and truth be told, it could be the attempt to make mags semi-universal that is causing most of the mayhem, not the extractor claw per se. IIRC, per Speed, Original Mausers had specific mag box and feed lips engineered to every cartridge. Most if not all susequent commercial mass producers do not. Just exactly when and how the case leaves the mag makes a big difference in the extractor's ability to grab it correctly.

No wonder many of the mass producers dumped the Mauser claw and went to variations of push feed...
