It seems like both of my CZ 550 Safari rifles operate a little differently than my M-70 Classic. With my CZs, the cartridge pops out of the rails and gets under the bolt face/extractor but it does not fully engage until the cartridge is entering the chamber. I can visiually see the cartridge rim quietly snap in place when it is entering the chamber. With my Winchester, the catridge pops out of the rails and into the bolt face/extractor at a fully engaged position. It seems as the CZ extractor is much tighter than the M-70 and would require some force to fully engage the catridge rim. Which of these two ways is a true Mauser design? Any insight will be greatly appreciated. Thanks. Ming

Ming,

I do not have the answer to your question but I recently got my CZ .416 back from a few adjustments and noticed that my extractor had the same shape as yours ie. a little bow inwards. It works fine however.

Hey PC,

It seems like the bow on the extractor body is "normal" and should not affect the functionality. When I have more time, I will probably take the extractor out and straighten it out a little so it will look right. Thanks. Cheers! Ming

All the control feed needs to do is "CONTROL" the cartridge from the time it comes loose from the magazine, till it is chambered and fired,Then extract the case, and eject it from the rifle. Once the magazine looses the cartridge, the bolt can be worked in any dirrection, and it still has hold of the cartridge, that is what CRF means. To test the effectiveness of this system, with the chamber empty, and the bolt closed, pull the bolt back, then force a round off the top of the magazine, but don't go all the way home with it. At this point, pull the bolt back, and see if the cartridge comes back with it, and ejects from the rifle. If it does you have a working CRF system. It matters not if the cartridge is fully engaged as long as the bolt can make it go either way, after the magazine is no longer holding the cartridge! The Winchester is different in it's completetion of the process, and the Winchester is closer to the Mauser than the CZ, but both are true control feed, and are, IMO, far superior to any push feed rifle for use as a DGR!

So Mac, in your opinion is the M70 the better action ??

Mac, thanks for your reply. Now I would like to ask your opinion on a narrowed down question.

I am going to purchase a .375 H&H at some point to match the CZ .416 I already own. As far as a .375 H&H go which would you prefer the M70 SS .375 or the CZ 550 .375 H&H. I would just go and purchase an M70 .375 when the time arrives as I have never owned an M70 but I hear a lot of bad reports about them on this forum.

Sorry Ming I'm always interupting posts with my own rubbish but I just like toget as many different opinions as possible about things.

PC,

There is nothing to sorry about. We are all here to share info. I hope you will find what you have been looking for. On a side note, check out the new Charles Daly Mauser replicas. They make both blue and stainless actions for the 375 H&H. As a matter of fact, I have been waiting to get one myself. I hope that they will be here in the US very soon. Brownells will have these new actions available hopefully soon.

MacD37,

Thanks for your reply. However, I have to disagree with you about your comment that the CZ 550 is not as polished as M-70. I got two M-70s and two CZ 550s and I can tell you that there is no way the M-70 can match the fit and finish of the CZ 550. The CZ 550 had the bolt assembly polished very smoothly so as the feed ramp and follower. The fitting is also very good for a mass-produced $650 product. My M-70 had the bolt body jeweled from the factory but it was one lousy jewelling job. There is a lot of tool marks on the bolt body. The bead blasted finish on my Classic Stainless was also very lousy with some unfinished spots. The bottom trigger guard and floor plate fitting was exceptionally poor. It was so poor that the floor plate would not close completely. Also, that famous claw extractor would not bite the case head tightly like the CZ 550 does. Oh well you get the point. Cheers! Ming
