CZ Model 527 Issues With Ejecting

[L.Sherm]

I probably started all the confusion thinking rem 700 before the light turned on but it you read post 12 I corrected myself

I checked the ejector this afternoon and cleaned it. Then I placed a live round in the chambered and it ejected fine. Next I tried a fired case and it also ejected. When the weather clears enough for me to do some target shooting, I'll see if the ejection issue is solved. <Thanks>

I'm glad it worked for you so far. At least from now on, you will know where to look if you have ejector issues.

forcing the Mauser style extractor to snap over the case rims when attempting to single load rounds

What causes the extractor to snap over the rim when single loading but not when feeding from a mag?

 

[L.Sherm]

It has to go out and around the rim, from the mag it picks up the brass from the bottom just like any other control round feed action.
If the extractor has the right angle on it as it hits the brass it will push it outward and around the rim of the case. If the angle is to steep the bolt just stops.

The CZ is controlled round feed, just like the Mauser '98/'96/'95-'93 and the Springfield 03 and 03A3, and the pre-64 Win 70.

Tomorrow ill see if I can take a pic of a hornet extractor ive worked on that single feeds without the mag and compare it to my 20PPCAI bolt extractor theres a big difference in the angle face of the extractor

Ive shot thousands of rounds out of my hornet actions that are set up to single feed and still work flawlessly

If you look at the extractor, think of it as being on a spring, albeit a long flat spring. The front of the extractor is chamfered to allow the cartridge rim to push the extractor out of the way as it is moving towards the chamber. There is room enough in the receiver to allow this to happen.
When feeding from the magazine, the cartridge is pushed forward just like with a push feed action until it is released from the magazine. At this point, the cartridge slides up the bolt face and under the extractor. The spring force of the extractor holds the fired case to the bolt face while the bolt moves rearward until the ejector makes contact with the rear of the case. A combination of the rear motion and the spring action of the extractor throws the case out of the action. It seems like every process in the action is controlled by a spring of some sort.

I had to work on the extractor on my 17 Badgers to get them to feed (snap over the rim) single shot without the clip.
Maybe CZ changed there extactor angle after I got mine.

You could be right. That would explain why so many folks say that it can’t be done. I was also thinking that some cartridge case might just work better than others.

As you can see the hornet extractor ( left) has more of a angle to help snap over the case vrs the 7.62x39 one on my 20PPCAI

Hi All, I have a very accurate CZ 527 in 7.62X39 M/M, which recently developed an issue with ejecting fired cartridges. The fired cartridge cases pull easy out of the chamber but remain on the bolt, thus not "Kicking" the fired catridge out of the action. This rifle is very well taken care of, so it's not a dirty action problem. Just wondering if anyone know why this CZ 527 is doing this, and what I can do to get it to eject fired cartridges normally. <Thanks>

Hi,
not all 527 extractors are equal, some do not suit the rifles they are fitted to, ( I have heard of this on new rifles also ) also when extractors are sold as a spare part they need to suit individual different size cartridges, however in my country at least they seem to have mislabeled them, or mixed them up, and had them in the wrong parts bin somehow.
If an extractor for a .223 for instance is supplied for a 7.62 it will have too greater claw length and a cartridge may still be picked up and chambered, but on extraction ( ie further back in the bolt withdrawal ) the excessive pressure on the extractor claw will force the middle of the side part outwards and jam the bolt in the action and not reach the tab that knocks the case out. Check that the bolt is reaching the same rearwards point when a cartridge is on the bolt, as when there is no cartridge on the bolt?
Mike 527.
