CZ .22 misfire

Recommended Posts

I've a CZ 452 .22 and occasionally I get misfires from it. I'm using remington bullets which, main reason they are cheap. The striker is hitting the rim and leaving a dent. They will normally fire if I recock the bolt, but the other day it just wouldn't go at all so my mate put it through his CZ and it fired first time.

 

I took it back to the gun shop after I first bought it and they said they had changed the spring. Should I try another spring, a new firing pin or different ammunition?

I've stripped the bolt down in the past and lightly oiled it. The only think I can think if it's not the ammo is the firing pin in slightly too short. I'll maybe have a go with some other bullets.

 

All of the parts for the CZ bolts are readily available so hopefully this can be relatively easily resolved if it is not the ammo.

 

Someone mentioned it earlier, try another complete bolt if you have the opportunity!

 

I'm still no fan of Rem subs but historically my CZ got on well with the 1500 ft sec Yellow Jacket HP! :good:

Them remmies tend to have thin rims.

 

That aside many a 22 gets crud in the bolt and limits the pins travel..

Some folk dry fire their 22 and cause the pin to strike the breech face not doing any favours to the pin or breech face.

 

I have in the past had to stone the part of the pin that limits its travel. Yours may just need a few thous of an inch more, it will be next to nothing to remove from the stop.

Don't worry about the spring.

If you can measure the pin protrusion and then carefully remove a slight amount from the stop you should get a little more pin protrusion and that should cure that.

 

No dry firing a rimfire please!

Do you mean the shoulder before the pin narrows down? Would I have to just go to the gunshop and order a new pin? I don't suppose you can order them online.

The shoulder yes, what ever or where ever the pin's travel is stopped.

 

Wrap some 600 wet n' dry around a small file or similar and polish away, it won't need much!

 

If you get a new pin by rights it would need fitting and checked for function just the same way!

Try some different ammo before messing with the bolt.

 

I have up with Remington subs a long time ago.

Winchesters are my normal choice but am

Just trying some aguila hollow point subs @ £35 for 500 they seem very good :)

Strangely,despite others finding them poor,I always found Remmy subs OK in my 452 but the last batch I have bought are absolutely rubbish.Some "pop" & some only go "phutt" plus many only fire the second time you try them,just as though primer not all the way round the rim.My 452 has an uprated (J&P) firing spring & has had no firing issues apart from this batch of Remmies.

Clean the bolt first, mine had a build up in it the first time I did it. Then ditch the eleys..not many people have good things to say for them! My 452 enjoys the winch subs, not heard many bad reports from friends with a rimmy. 80yrds bunnies are easily achievable with them, you won't be disappointed:)

Do you mean ditch the Remingtons?

My last box of Rem subs had 3 misfies out of 100, it also had several that went supersonic and several that went phut, terrrible stuff!

 

 

Remmy subs are ****, cheap but ****... I found them so inconsistent you could barely zero the rifle, I had misfires, slow burns, supersonics, phuts... the works... truly awful ammo.

 

 

I've never shot anything worse. Awful stuff virtually unusable. Try some different ammo first.
