Advice & help please, brand new CZ 452 Misfiring?!

Hi there, just after some advice, as I am as fresh as they come to fire arms. SO, I got my brand new gorgeous CZ 452 Lux LH with a brick of CCI Standards, Woohoo! Excited much. Never used a firearm before... ever. Got to my old mans place actually feeling quite nervous to pull the trigger for the first time, so I feed a cartridge and it goes 'click' :wtfsmilie:. This sent me into a nervous fluster as I wonder what I am doing wrong, carefully I take the cartridge out and put it to the side, work the bolt and fire a good round which almost instantly eased my nervousness. Problem is, out of about 100 rounds I got 12 duds, which in talking to a good mate reckoned it was 'way too much, there's gotta be something wrong'. Rang the shop, they said bring it down, I brought it down, they cleaned a whole lot of grease out the bolt and replaced it with some other grease, fired it 30 times with no issues and tell me 'all sorted'. I take it to the old mans, fire it, still happens, rang the shop, shop gave me a whole lot of different ammo that was lying around and said it could be the ammo, use the ammo and I notice its starting to improve a hell of a lot, to like 5 duds out of 100. However it is still misfiring, so the shop gave the bolt a bath in oil and said just keep firing 'it'll losen up'.

Everyone's telling me 'oh its so strange CZ's are one of the most reliable' yea yea yea :ORLY:. I do believe it though.

Has anyone had any similar experiences or could provide me some advice on new .22's doing this? It would be greatly appreciated.


Cheers

Get them to replace the rifle. :D

I'm with Daggers_187 on this,take it back to the shop and get them to sort it out, they may have to send it back to the importer.
It's not your job to trouble shoot(no pun intended!) a new factory rifle.

Yeah. If they're sure it'll sort itself out, then they can have it back. Sounds like some fucked up shit going on with the firing pin/firing pin spring.

Fair trading act etc. The rifle is 'not fit for purpose'. Ask them to remedy. Simple.

A mate just ran 400 through his. Not one misfire. Something's amiss with yours !!!!

For what you've paid there should be zero expectation of faults/misfires. Make it their problem. Not yours.

If the assistant even remotely looks as he's about to turn on the bullshit switch, ask to speak directly with the manager. Don't piss around. You've paid serious money. Let them earn it.

What SiB said :thumbsup: mention all the words in the first sentence.

What shop ?

Also keep the mis-fired rounds and show the shop them, could be light strikes on the rim.

"Cleaned a whole lot of grease out of the bolt and replaced it with other grease"

Sounds a bit suss mate, very light oil will suffice in a rifle bolt, grease will only slow down fast moving parts like a firing pin, and can be a source of light firing pin strikes.

Shouldnt do it.
I have a Brno bought it new about 1990.
Cannot recollect a misfire and the gun has had thousands rounds through it.
Get them to replace it.

I shoot around 150 to 200 rounds of cci weekly and have done for years. CCI is a very reliable brand.Your rifle has a fault. Excessive head space or firing pin fault. A competent gunsmith will ID the fault quick enough.Get the rifle replaced.

something is fishy, i have a CZ452 my 8 year old has put nearly a 1000 rnds through without one problem, its absolutely awesome rifle...
We have used all sorts of ammo, CCI and winchester with subs, standard & high velocity... it eats everything without problems.
Grant

I have exactly the same rifle (even LH). Never missed a beat. What's the ammo?

Yeh. Unless the ammo is Sus as this rifle should not miss a beat.
Ask for a new one mate. I would; you actually have a bit to loose if you don't.
I've had probably 5 misfires over the years and that's from 000's of shots.
Good luck.

This ^^^

Agree with @7mmsaum +1

Viscous grease can accentuate any issues in the slowing of the firing pin and issues around the function of the bolt.

However, You might also want to try if firing a round and when getting a click, lift the bolt vertically until you hear the action re-cock and then drop back down ensuring its right down and try to fire again. If it fires- Then you've removed faulty rim fire ammo from the equation and its likely not locking the whole way down into place giving not giving the firing pin a solid contact it needs and therefore causing a misfire.

Just check this isn't the case as you can easily do this with a quick lift'n flick load when it hasn't completely locked downward into place.

I also have a LH 452 American and this so times happens when I'm doing the rapid timed shoot part of my card. Especially when they are new it's easy to not realise you've done it.

Hope this is your fix...

quite a common issue with the 452's. The ejector claw and firing pin need tweeking by a gunsmith...take it back to shop and get them to return to the NZ Agent to get fixed

The fact that the misfires reduced after the shop cleaned out the original grease makes it possible that they didn't get all of it. There may still be some grease in the far end of the channel where the firing pin spring fits in the firing pin. This can cause the spring to slow down to the point where it doesn't have enough force for the firing pin to deliver a full blow to the rim (primer) of the cartridge case. It's not that easy to clean out unless you squirt some brake cleaner or similar down there.

Sparingly use a good quality light oil on the firing pin spring.

as 7mm swam says it could be jammed with storage grease and could be a simple case of pulling the bolt apart and giving it a clean don't do it yourself as of you do it and something is wrong you would have voided warranty tampering with it could also be a broken firing pin if it was on the shelf people dryfire them which you should never do with a rimfire my 452 fired over 39000 rounds before I upgraded and the only misfires were faulty rounds which is quite common with 22 ammo

take it back to the shop its not your problem

Take it back to the shop ASAP ... don't play around with it.
