CZ

[Tungsten 0]

I recently purchased a CZ 452 Style with Parker Hale Mod as a cheap and cheerful .22 rimfire rabbiting rifle. Did a bit of research first and CZ rimfire was in the top 5 of Sporting Shooter rifles.

I was not expecting competition type grouping, but maybe a 1†at 50 -60 yards, enough to give a clean kill. However when I took the rifle out to try for the first time (supposed to have been zeroed at the shop at 100yds)I set up a target at 65yds aimed a little low and bang not even on the A4 sheet size target. Me and a friend then spent 25 rounds each of Winchester Subsonics trying to get a consistent 3 shot grouping, they were all over the place. At first we thought it was the scope, so we change it from the Tasco to a Leupold another 25 Winchesters were flying wild, no consistency at all, the rifle was well supported front and back. We tried 30 Laupa target rounds thinking it might be duff ammo, but there was no improvement. Using my friends Sako we were able to get extremely tight groupings whatever ammo we used. So after running out of ideas we packed up after 4 hours. My friend even looked down the bore with a bore scope to see if there was anything obvious throwing the shot out, but nothing.

Any ideas????

Tricky one that...

Make sure everythings tight.(bedding, mounts etc)

Take the mod off and see if the problem remains.

If not, take back to shop..

Take the mod off

 

 

thats the first thing to do & secondly, have a look at the crown on the barrel..

 

i had a ruger that couldnt shoot for shit, as soon as i got it re-crowned it was bang-on..

 

 

just to add, have a look inside the end of the moderator & have a look if the bullets have been making contact with the end on the inside, could be that the mod isnt bang-on, i also had this same problem with a theoben with a badly fitted mod...

if it's a floating barrel,try sliding a piece of paper along to make sure it's not catching anywhere if it is try slackening the screws off a half turn,then tighten them alternating each screw and keep trying the paper along the barrel to make sure it's still free floating

Mods are the main cause of this type of problem. I know that a few CZ owners have had trouble with the factory screwcut not being completely flush.

 

This would be your first port of call.

 

Then as mentioned check for even the slightest marks or dents in the crown as this can affect accuracy no end.

 

The Parker Hales have had a bit of bad press so let us know the result.

it wont be a floating barrel because the barrel on the style does touch abit but its not worth the bother trying to take some out of it as its plastic stock. if it was wooden then yes but on the plastic stocks it dont make any difference.

 

i have a style and it groups the size of a finger nail at 60 yards with eley subs. it is super accurate so it wont be the stock mate.

 

what i would do is try with eley subs, try with mod off, get the trigger kit for it your be surprized how it will help your shooting. but like you said if it isnt grouping then it could be the crown. look down the barrel from the crown end and see if you have any knocks in the crown or if there is any pitting in the barrel before the end.

 

it sounds silly but make sure the mod is tight to.

 

but 1st rule other things out like scope mounts are tight, shoot with mod off. if that dont work it will be the crown

As above... Mod, bedding screws, crown & scope mounts. If all start zeroing at 25 yards and work back to 60. You are within your rights to take it back but make sure you check all this before so you don't look like a nob. I wouldn't put too much faith i bore-sighters either... generally enough to get you on the paper at 25 but not spot on.

As I said we went through every thing tightened screw, changed the scope, used different ammo, different shooters, checked the crown with a bore scope. I shot with my mates Sako just to rule out me as the problem and I was getting groupings as big as a thumb nail. One thing I didn't do is remove the mod and try it! so my money is now on that. As I have only had the gun from new for 3 weeks I am taking it back to the shop as obviously there is some thing not right.

I was expecting a lot from this CZ as I did a lot of ground work first and read quite a few good reports on the internet so a bit disapointed, but I like the look and the feel of the gun so if they can sort it I'll be happy.

Is the trigger kit difficult to fit?

[stillair1 16]

Trigger kit available from SYSS. Original Brookes kits seems hard to source. Quite easy to fit just got to tap out one of the pins which can be stuborn. Ten minute job iirc. It is possible to catch the fired bullets undamaged if you are suspecting the barrel or mod.

I owned the same gun but in .17hmr 6 months ago,had to sell it due to the barrel being pushed to one side and now own a sako quad.I have found that the sako is more accurate than the cz but youve got a serious problem with yours.Just a thought babout the shop you bought it from that said that they zeroed it in at 100yards.In my opinion this disance for zeroing a 22LR is way too far.Take it back and ask them how they could get it zeroed at 100yards when you cant get it zeroed at half that distance!!

good point, didnt pay attention to that... why would they zero it in at 100yrds ???

 

i personally zero mine in at 65yrds...

[SNAP SHOT 194]

just to add you should shoot it in, clean after every shot..... for between 30 to 50 rounds or more if you fancy.............seeing its a new gun

second check the scope mounts, all screws etc on the rifle also..............the shop may only have put a bore sighter on it enough to get you on paper.....

It will sort its self out, it is a good gun in principal. i have one and it shoots fine, use it everyday..

sounds like the crown my bosses rifle was the exact same till he got it re-crowned, rimfiremagic dont do the brooks kit any more, they have there own trigger kits now for the cz's , only £10 and very straight forward to fit and with better instructions than the brooks kit.

how you getting on with the cz style,i have the same gun and it shoots spot on,i have the brooks kit on mine as the trigger out the box can be silly heavy,and cause you to struggle to get good groups,especially if your used to air rifle triggers,i got my brooks kit direct from usa,took a week and about £8.00 allin,and it is a doddle to fit,just be sure to do the drop test,and you dont allways need to put the pins in,mine is spot on with just a spring change,but went off on the drop test with a pin,on the same spring,just mess about,it will improve your shooting big style,and you soon be doing this,atb,ianhttp://i220.photobucket.com/albums/dd220/ianace32/PICT0001.jpg
