457 22lr ejection issue

My cz 457 extracts fine but has difficulty feeding the last round in my 5 round mag,
I'm thinking that maybe the ejection of the fourth round is messing with the last round,but I have the tx1 as well and find it to be a much better all around 22lr and choose it 6 outa 7 times.the other complaint I have about the 457 is you have to hold tight when operating bolt or your going to pull it outa wack.the tikka is smooth as butter.but both put the anschutz 1761 22lr to shame.
 
some Savage rimfire owners experiencing the extraction issue added a second ejector spring on top of the original one. Perhaps having more tension on the extractor by doubling the spring would prevent it from slipping over the case's rim and extract/eject more reliably.
 
The 10 rounders mag that came today has a slight difference than the 5 rounders that came with the action, the follower on the 10’s seats a little bit lower than the 5’s, the rear tab is more thicker, did try loading/ unloading , the 10’s ejection is more consistent and better, hope this solved the ejection , 5’s in top

Update, so the new 10 rounders ejects except for the last round, way much better than the 5 rounds the came with action, might keep the rifle
 
Even the 10 rounders Poly has the same issue with the 10 Steel mags. Had the chance to show Casey of TacOrd the rifle, its the Extractor thats causing the last round Ejection issue, this happens when after the last round is fired the magazine now is empty , there is no ammo thats pushing the fired case to the bolt face. With enough extractor tension the spent case will remain in the bolt until it hits the ejector. Casey is willing to experiment with the profile of my extractor and holder but would prefer to have spare parts just in case lol, emailed Wolverine asking for parts availability.
Btw already the RMA from them, but what’s the point of sending the rifle if they don’t have the parts, it will just collect dust for the next 10 months
 
I found the same thing. I have 5 and 10rd mags, poly and steel, and have last round failure to eject with all of them.
Replaced the holder and spring in the bolt and it didn't help. Just ordered a 455 ejector from Wolverine, as the 457 uses the same ejector. I pulled my 455 bolt out to look at them side by side, and there is no question that the 455 bolt holds a round more firmly.

Ejector not the Extractor?
 
I have had the failure to eject on the last round only with the 10 round mettle and poly mags. 5rd poly 0 issues using poly. there definitely is a difference in the fit and finis of the 10rds mags.
 
After a thorough inspection, its the Extractor thats causing the issue, no enough tension to hold the fired case on the bolt face, with no round on the mag, nothing can push up the fired case, will work with still a round that helps retain the fired case. Wolverine is sending me the parts, but it will depend when CZ will ship out the parts, very disappointing I know, don’t want to do anything yet to the Extractor and Holder until received the parts, just in case I mess it up.
 
Are you just replacing the extractor and holder? Or are you thinking that you have to modify the holder/extractor to get things to work properly?
 
Will try dropping it in, if doesn’t work then modify, but will wait for the replacement parts before doing anything. I can still shoot the rifle except for the ejection failure on the last round, maybe should get a 25 round mags, lol

Hi
First time shooting the rifle, having some ejection issue, any fix or recommendations?, rifle shoots great accuracy wise, 0.6” @100 with SK Std plus, its a shame its not that reliable at present, hope to find a remedy. Thanks

My buddy had the same issue, he had to send it back for warranty work the chamber was too tight. They had to do something to the chamber

It wouldn't even eject CCI std.

Completely ridiculuos
 
Update on the last round ejection issue for my 457 MTR.
I ordered a 452/455 extractor from Wolverine (product #CZ15130063001ND), and it has completely fixed the rifle!!! I just put 200 rounds through the rifle, with all three different mags I own (5rd steel, 10rd steel, 10rd poly), most of which were only loaded 1-3rds to test, and it ejects the last spent casing with authority now! doesn't matter if I pulled the bolt back slow, normal, or with pace, it ejects like it should have from factory!
I initially installed a new holder and new bolt spring, and neither of them made even 1% of an improvement. the new extractor fixed my issue completely.

I should have taken pics, but I put the original 457 and new 452/455 extractors side by side to compare them and they're not 100% identical. when installed the older 452/455 extractor sits slightly closer to the bolt face and also closer to the firing pin hole than the original extractor did.

Looks like it's now out of stock, but this is the one I installed:

hope this helps someone.
 
Hi, sometimes with your new rifle, the tolerances are tight that it might take numerous rounds before everything starts to loosen up a bit. Try taking your bolt apart and give a through cleaning and then a lite lubrication also will help

Looking at the product picture on wolverines website, it seems the extractor has a bit of a curve shape under the claw.
CZ15130063001ND.jpg

Can anyone confirm they have that on theirs? Mine seems to be a straight edge. I wonder if a straight edge is causing the extractor to not contour to the rim of the case and make extraction/ejection a bit more finicky. Would also be curious if anyone else has added this rounded edge themselves and had better luck? Seems some folks on snipershide/rimfirecentral may have done this but with the part out of stock I'm not sure I want to go mucking with my only set of extractors. These same people seem to have also had some luck by removing a few thousandths of an inch of metal from the pointy face of the non-ejection side shell holder.

I haven't had much for extraction issues with SK but my latest case/batch of CCI SV has been giving me a lot of grief (although the previous case did not, go figure. Could just be CCI quality control...) Mine likes to drop shells as soon as they get out the the chamber, which causes the empty shell to sit on top of the next round and cause jams. This was very repeatable at home with spent casings. I bent my extractor spring a bit tighter and from testing it seems to be holding onto the shell much better, although until I get back to the range with live rounds I won't be sure.

After well over 2k rounds and a few nights spent cycling the action to smooth it out, I'm inclined to think these issues getting worse/more apparent are not new gun syndrome but perhaps poor tolerance stacking between the ammo and the extractors, at least in my case.

My 457 does the same. It will eject spent cases from higher end ammo, but won’t eject cheaper end ammo. It won’t eject hardly any unfired ammo. I know your frustration, following along to hear what folks have done to fix the issue.

Hey Decker
You may find other makes that don't eject
unfired rounds , my Annie 1710 doesnt extract any unfired CCI
and a Cooper 57m , either doesn't chamber lower end ammo .
 
Still waiting the parts from Wolverine under warranty, for the time being I did filed the extractor and holder on the inside to make it closer to the bolt body, so it’s working right now,,, hopefully the parts will arrive soon
