CCI Subsonic HP Problem


Recommended Posts

Hi all,

 

As I'm new to firearms, can anyone answer this. I have a brand new CZ452 American .22 and bought 500 of the rounds in the title at the same time as the gun.

This was on the gunsmiths recommendation. I have used around 150 and have had quite a few that are difficult to chamber and when I draw the bolt back the unfired cartridge leaves the bullet in the barrel and deposits the powder into the bit where the mag goes. This then means that i have to rod the barrel from the naughty end to clear the bullet and clean the powder from the bolt and mag. :good:

I know to expect fliers and have had quite a few but this doesn't seem right to me.

 

Can anyone give me some advice. I can see a change in rounds coming on but need to use what I have first.

Bing Bong,

 

Rimfires are notorious for being selective when it comes to ammo, try all the different brand you can get your hands on to see which performs best, also if the gun is new it will take about 500-1000 rounds to wear in, if a round becomes stuck try taking it out with the tip of your finger nail as usually it just needs the first few mm of movement, also keep it lubed up.

 

or if in a safe place fire the round into the grass/ground and then extract it (as you usually find it is the unfired rounds that are the problematic ones)

 

Regards,

Wymberly,

 

I was talking about the extraction problem but you are correct.......... about the rounds not chambering, i recently had this problem with a 10 shot mag for my CZ style, it was not pushing the bullet tip of the round high enough....it could be this.... appologies for not reading the OP in detail...

 

A freing bought a brand new CZ silloutte and when you champered a round and pushed the bolt handle down the gun fired!!! he took it back to the gun shop who sent it back and said they had never heard of this happening, it made my friend extremely nervous when using the new rifle but all was ok with it...

 

Regards,

I agree entirely with wymberley,

 

It sounds like the chamber is either too tight or too short causing the bullet too get stuck in the lead into the rifling. By all means try another type but I would take it straight back to where it came form.

 

It could well be the lubricant coating on the bullets causing the problem, I know with Eley Match that some will chamber easily and some are tight. But the last thing you want to be doing is cleaning each round.

 

I like Winchester ammo and have not had a problem with it like I did with Remington in my Ruger

Hi all,

 

Thanks for all the replies. I would agree with Wymberley if it was all the rounds that didn't chamber, but it is only the odd one so I'm maybe thinking that it must be rounds out of tolerance. I just never expected manufacturing tolerances to be that poor. Looks like I might have to try Winchester or Eley.

 

The rifle groups O.K. with the ammo, it would be interesting to see how much better it will get.

The gun needs to go back and be checked . It sounds to me you have a very tight or short chamber ,this could cause exessive pressure and damage to the gun and in the extreame a burst barrel . I personally wouldnt shoot it again untill it has been checked out .

Bing bong,

 

Absolutely. Both the barrel/chamber and ammo are made within given tolerances. Unless you have the necessary precision measuring equipment you will not know which is causing the problem, it could be both. Bulk production of 22RF sporting rifles and ammo means that they aren't the most precise bits of equipment on the planet. Harnser's advice is good.

 

Cheers

Same problem for me too.

 

Went and purchased 500 CCI today and thought I would put 100 or so through my Sako Varmint, at first I thought my bolt was sticking because it was a nightmare to chamber the round and close the bolt.

 

After trying to feed ten rounds through I knew I was risking some damage as I was really forcing the bolt hard, on closer inspection I noticed that the rim at the base of the round was much thicker compared to my Eley Subs and the bullet head was wider than the Winchesters and Eleys. I even asked my poor sighted wife and she clocked the difference straight away.

 

Mine are going back tomorrow and never again will I buy them but, from what you’re saying it seems that there’s a major manufacturing problem.

I took the rounds back to Kieths of Saltburn and because I had opened and used 8 rounds from a box he would only replace 400 of them with RWS, and that’s after charging me £40 for the CCI’s :lol::P:P

 

My point to him was I had paid for .22lr rounds for a .22lr rifle and they don’t fit so surely all of them should have been replaced?? Anyway I now have to wait to see if CCI have had any other rounds returned before I get them replaced. :):D:D

 

Never again will I buy CCI’s, nearly ended up damaging my Sako trying to chamber them…. :sly:

A mate of mine is going to bring some other rounds for me to try through the gun, but it looks like I'm going to be returning the ammo bought and getting the gun checked at the same time. Like I said, it's only 1 in, say 15 rounds that wont chamber, the other 24 chamber fine. You would have thought that a reputable gunsmith would have known about this problem, I guess he saw a virgin firearms cert and saw a chance to get rid of old stock no-one else wanted. :lol:

Bing -bong ,

The problem is more likely to be ammo ,but you carnt ignore the fact that the bullets are touching the lands . This is a desperate problem to have with a gun and can cause high pressure . The gun definately needs checking out for your own piece of mind .

I agree with having the rifle checked out by a good gunsmith,but, I won't use CCi subs in my Cz because of the problems with chambering being so tight,and some will go supersonic.I now use Winchester X subs,no problems at all,just my opinion.

I havn't used the gun since identifying the problem as not one due to the gun being new, I've just got to wait for the chance to get back up to Churchill's at Dereham. Its a fair haul for me as I work six days a week. Makes me think that I should have supported my local gunsmith but he was £40 dearer on just the gun alone :blush:

Mind you, that's typically Norfolk of me. Dereham is 30 miles from where I live.............now where did I put my passport :blush:

I am sure Steve at churchills will sort it out for you .

As others have said, I agree it would be a sensible exercise, to get it checked out if it does this with other makes of ammo.

 

However, CCI are notorious for having slightly 'long' rounds, and I have a similar problem with CCI subs in my Sako. It produces lovely groups but as the Sako has a target oriented chamber when you close the bolt it sets the bullet into teh lands of teh rifling. I also cannot exctract them once chambered so I have to fire them out.

 

This is not a problem with the rifle, but it is with the ammo in that rifle. (this was my eye-opener into teh world of shonky factory rifle ammo...) `Be careful taking it to a gunsmith as thy may ream out the chamber.... DONT LET THEM DO IT, just use one of the many other brands of ammo that wil undoubtedly fit your gun.

 

As others have suggested above, get some other brands (winchester, RWS, Eley) and try them. I believe you will find that there are OK and its only a prob with CCIs.......
