Recently purchased a brand new CZ 457 Varmint in 22WMR - over the last two weeks have experienced multiple light strikes with various new ammo.

Misfires have happened with CCI, Federal and Remington. Current production ammo - no old stuff.

All misfire cartridges have fired on second try.

Inspected bolt - looks ok - cleaned and oiled etc.

Would appreciate all constructive comments regarding sorting this out and ideas of probable causes.

ALSO - has anyone else experienced this - ?

So far a highly accurate gun when it does fire.

Thanks D.
 
Did you dis-assemble the bolt ? And did you 'oil it' when re-assembled ? I only put a tiny match-head's worth of PTFE-grease and spread it across ALL inner surfaces of the bolt . . . no more than that. Do you have pics of where the strikes are on the cases ? Re-profiling is generally an improvement to firing probs - do you use this gun in 22lr also ? That would need consideration in re-profiling, too. Lots of threads about the 're-profiling' on RFC, as 45cat suggests.
 
So I spoke with the guys at the shop where I bought it who advised to strip the bolt and clean it good.

And, I watched some youtube videos on this etc.

It turns out that the firing pin has shed a fair bit of the metal plating on the right side of the pin and it appears to be coming off in tiny flakes.

Anyway, re-assembled, test firing, and all seems to be running good now with much deeper/sharper strike marks on the cartridge heads.

However IMO this is not good quality on a factory firing pin that has less than 200 rounds on it.

Does anyone know who sells a good quality aftermarket firing pin in Canada ?

Thx. D.
 
djm , There have been lots of CZs with that problem. Check out 'Rim fire central' CZ-site to see many posts about it. Now that you've figured out the prob and are running great (with Light lube), consider re-profiling (also info on RFC) to improve the strike position. The FP is designed to accommodate both LR & Mag so is Not 'best' for just Mag rims. Buying a 'new' FP is not the best choice since you may still have 'strike probs'.
 
might be a firing pin spring with an out of spec coil, a bent firing pin, or an obstruction of some kind in the firing pin channel. does CZ nitride their bolt bodies and other parts on their rifles in similar fashion to the CZ pistols?
 
I'll post a photo of the FP over the next day or so. the FP is plated and the plating is flaking off.

So far this is my only disappointment with this $900 rifle and in my opinion - poor quality component.

AND the Turkish Walnut is really "luck-of-the-draw" from what I've seen - my son has a 457 with a Beech stock and it's nicer...

Yes, if you buy online you may get 'nice wood' if the shipping dept doesn't have a buddy that wants 'better wood'. Luck of the draw is right ! I bought my VMTR used on EE, with "a couple hundred rounds fired", but lots of pics b4 buying. I 'washed' the stock several times with Dawn DW-soap, removing a lot of 'colour' until a white cloth came off clean. It came out a couple shades lighter, but NOT the "Mud" that many have received. Then I gave it several coats of MinWax Neutral Floor paste wax - quite durable. The grain isn't 'the best' IMO better than 'straight grain'. Pic below.
As I said there are a bunch of 'plated' FPs losing chrome, posts on RFC show that was common for a 'batch' that came from sub-con I believe was 'the story'. I'd advise taking a wire brush on that FP, maybe on a drill or grinder, to remove as much as possible any loose bits. Then, as I said I put a tiny bit of PTFE grease on the inner bits of the Bolt, including the FP. I've seen 'new' FPs in the USA running $75 or more, but haven't looked here in Can.

Buck1950 - thx for the post - beautiful stock you have there - the local gunshop said that for a warranty claim on the FP they would need the whole rifle - but I'm not shutting down over that - I'll just buy an aftermarket FP from people who know how to make one - and even though this rifle is a shooter - the quality is less than I had hoped for.

That being said a friend of mine (also in the game for 50+ yrs) said the 452's and 455's were better overall in the quality department.

Definitely luck of the draw on these stocks. But overall CZ has very nice wood. Some of the varmint stocks have been quite dark recently.
