My strange CZ455 only good for the first 2-3 mags?

[Tomek]

I definitely don't get an average of 20mm. It's more around the 35mm mark. I have noticed that people are very reluctant to blame the rifle. I understand this sentiment although i had a really good shooter test is last time with many different rounds and he's never seen a cz like mine. 1 box of t22 ammo (from before their manufacturing changes) from many years ago out of 17 is unacceptable. That's not likely to be a statistical anomaly as all other ammo just goes all over the place. The shop and he both said my scope is fine as well.

[Tomek]

The shop said they'll take it to a private range and test it for me. That's good. Will see what happens but I'm nervous as i don't want to get stuck with it over a marginal pass. Anyway, good luck to them. I'll know on Friday!

Yes this will be the worst outcome. BTW is there some sort of guarantee that CZ offers when it comes to accuracy? I mean, where do your expectations regarding average accuracy stem from?

I understand that the bedding has not been checked but how was the scope tested for that conclusion to have been reached? Was it a box test for instance?

[Tomek]

I checked the bedding of the barrel and it is floated and free of shiny rub marks. As for accuracy, you get people all over saying that 10c groupings are normal. And cz said 2 / 10 ammo should shoot well. A further 3 acceptably. Surely "well" wouldn't be > 1inch on any reasonable expectation.

Consumer law states that if it doesn't perform as one would expect ,I'm entitled to an exchange or refund. The kind of performance I'm getting is definitely not up to expectations.

In the end, if someone wants to buy my rifle for 600 go ahead. If it's really just a few tweaks away from perfect that should be a bargain. But i doubt the store would take me up on that offer..

Yes provided the issue is with the rifle (and not the scope / shooter), it should average under 1" @ 50m with select ammo. BTW I presume you're testing using match ammo?

Lots of good points raised in the above posts.
IME, entry/mid level 22 sporters which will shoot .5" consistently at 50 with proven lot numbers of target ammo. are the exception rather than the rule.
If a range rifle is required and you don't want to "tinker" unduly, then (funds permitting) you need to look at Anschutz, Sako, Cooper etc. It goes without saying that proven target ammo. and good optics are also part of the equation.
I'm fortunate in that I've had the opportunity to own some of the best production rim fires ever built over the years. Having said that, the Lithgow Arms LA101 is a LOT of gun for the money. I have an early and late model production version of this rifle - The new one (September 2016) is perhaps the best "out of the box" rim fire I have ever purchased !!!!

Here's a couple of examples of stock and customised rim fires sporters that will meet the most fastidious amateur range shooter's requirements.





I hope you get something sorted one way or the other re this CZ455 - Nothing more off-putting for a novice than an unsatisfactory rifle.

Yep I've tried elley sport, club and match. All crap. Meanwhile, my gf's range rifle got < 0.5inch with match. Results are the same if we swap shooters.

Again, I've achieved <0.4 inch with the first mag using cci hps on the first mag and a little wider with cheap federal hp. Accuracy drops quickly after that and by the 4th mag nothing works well no matter what brand.

[Tomek]

Thanks Allan. I'm really ok getting the anschutz. It's for life so why not. Lithgow is a good thing to consider too it seems.

This experience has been very discouraging as no matter what i try or who shoots its no fun spraying targets. To top it all off the suggestions make it sound like i gotta disassemble the NEW rifle and spend lots of money fixing it just to get a chance for it to shoot straight. I've done all that and it's still no good

I wouldn't be surprised if it get stuck with the rifle after some further misfortune. I can always sell it i guess. Plenty of people think its fine lol

Tomsk, just to be clear, the bedding you need to check is under and around the action. A floating barrel is no indication of good bedding. Maybe have another good look; unless your terminology is just misleading.

I didn't check that but the store would / should have when i brought it back the first time.

I wouldn't rely on that logic, it wouldn't hurt to pop the barrelled action out of the stock.

Yeah I'm open to that. What would I check for around the action? If it's shiny rub marks, I checked for that already all over.

Remove the two action screws and gently wriggle the stock to take the action out of the stock. If it hangs up you can tap the barrel on your mattress while holding the stock and the action should pop out. Look to see if there is any high points in the bedding, the action might be twisting on these as you tension action screws. Look for marks on the action then look for the corresponding marks in the stock where that part of the action sits, look at the recoil lug for any rub marks, it shouldn't really have any, shouldn't be too tight when it's seated. Finally look at the barrel channel paying special attention to the area where the taper begins. Look to see if it's contacting one side of the stock more than the other in this area.

I reckon you'll find some evidence of the action binding in the stock somewhere, if you do find evidence it will make returning the rifle for exchange a bit easier I reckon, use properly fitting tools to avoid marring your action screws.

If your not comfortable doing this see if the dealer will remove the action from the stock in front of you so you can have a good look.

I'm sure other members will chip in with anything I've missed, I've not had to deal with your issue but have bedded the action of my Howa .308 to make it more accurate.

[Gwion]

With a 22 the shiny rub marks are going to be pretty minute and hard to see.

I would just be taking the tact that it doesn't perform as advertised as you described earlier.

Unless you want to tinker, then you can 'paint' the action with a texta or such , put it back together and then shoot a box or two of any old ammo through it. Any high points will then show up as contact points from transferred ink. If there is an even transfer of ink then the bedding is all good. Clean up with a acetone afterwards. I wouldn't do it unless you are happy to tinker and keep the rifle. If you end up stuck with it, definitely think about working on the bedding. Happy to point you in the right direction if it comes to that.

Anyway. Good luck with it.
