CCI SV weak cycling one box

I am weirded out over ONE 50 round box of CCI SV that shot weak. So weak the empty was still in the chamber and the hammer not cocked.  Weird part is I started at one end of the box with about 20 straight all weak.  The next 10 were mixed weak and strong.  Then the last 20 were mostly strong cycling.  This was over two days.  This wasn't the gun or a warmup thing as I fired other ammos just fine within the 20 weak shots.  The lot number is B24T57.  I have 2 bricks of it.  Sample strings shot from other 5-6 boxes of the bricks shot fine.  Again this was repeated back and forth with different ammos.  Bad, good, bad, good, etc. 
In short, the rounds in one end of the box were bad, the other half mostly good. 

Does CCI have a bad ammo lot report line?  Anyone have similar experience?

I'm currently trying to shoot through a 500rd box of CCI SV that is loaded very light.

I get about two jams with every magazine, in two M41's that otherwise work perfectly.
The fired round is captured between the barrel and the next round in the magazine.

And it is the ammo, not the guns, or the guns extractor.

Still super accurate, but about a third of the rounds are noticeably lighter than the rest.

Jack,

I'm currently experiencing similar problems with case lot #D13ZA06. Same cycling issues as you, plus misfires. Go to CCI'S website and use their contact info. I'm shooting through this case for training and keeping all the misfired rounds. They asked that I send the misfires to them. Problems occurring in three different pistols. I won't use this ammunition for matches.

The ammo guys want you to report problems with their .22 ammo.  I have sent cases back to Federal and Winchester for evaluation.  Each time they paid the freight back and replaced the ammo with a new lot.  I just sent a case back to Federal.  It was their 711B.  Had lots of poofy rounds that would not eject.  They had UPS pick the ammo and two days later, I had the replacement ammo.  The new stuff shoots a lot better than what I returned.

Wow.... I thought it was just me.  I actually called KC to set up a time to get my Model 46 into him for repair.  I thought some felt weak, but this is the first time I've ever had an issue with CCI standard.  I'll try another some from another brick and see if that makes a difference.

Just a follow up.  New brick, and all the problems are gone.  I sent an email to CCI last week but no reply yet.

Just to add to the conversation I too had weak cycles with CCI SV. Of course it didn't happen at practice, but during an Action Pistol match. I was doing very well during one stage and had a failure to cycle and lost 10 points. I was wondering if it was my 41 or the ammo; I guess it was the ammo.

Any weak or otherwise weird 22 ammo I get ends up through my Henry lever action or my 617 revolver. Both of those guns will run anything. 
 However, next time I run into ammo problems I'll let the manufacturer know and see what happens.

Another test shoot of this CCI SV.  There are normal cycle and very weak no cycle rounds IN THE SAME BOX.  Unbelievable.

Jack H, I have similar issue with CCI SV, and it exhibited itself on one of my HS Victors.  I have occasionally light strike, and round doesn't go off.  However if I cycle slide manually without extracting round, - it goes off normally.  I believe, that underlying reason is incomplete cycling generated by previous round.  Although previous round went off and was extracted and ejected.  It is sporadic, and cannot be traced to any other constant like same magazine.  Wonder if anyone experienced the same.

In my case, the rounds all went off.  Strange though, the first 20, that is the first 4 lines of the box at one end, were ALL weak.  As I shot more 5 shot strings, 5 round line after line across the box, shots 21-30 were about half weak and half normal, randomly.  Shots 31-50 were mostly normal with just a few weak rounds randomly within.  And during those first 20, I did shoot some of a different brand and they shot OK.  

I also shot 5 or so from a few more boxes of the same lot (I have 2 Bricks of it) They shot OK.  Maybe I should try the other end of the box.  Again, all the weak rounds went off, and the empty brass was in the chamber each time.

I have written CCI via their "contact" page two times.  No response yet.

All my failure to cycle or weak rounds came from the cardboard box, however, when I use the plastic box rounds I have no issues. I am wondering if the problems noted here are from the cardboard box ammo.

I have been shooting the cardboard boxed CCI SV for quite a while.  I never looked at lot numbers.  It has always been good until that one box.  CCI has responded.  Said the lot number was 2012 made, and no reports previously. 

The same type CCI in unknown lot numbers has shot very well all along.  Especially a couple times from my Rugers.  One iron sight Ruger shot it offhand at 50yds; 8 tens and two called OOPS shots.  My fault.  Another Ruger at 25yds arm rested a one hole string with dot sight.

Kroil could do that to paper box ammo. I swear that stuff could wick up and down thru almost anything. It does sound a little like a contaminate on one side of the box.

No Kroil in the neighborhood.  Box was brand new condition

It could be that the priming compound from that batch wasn't settled or was handled roughly in transit.  That way, you aren't getting a complete burn.  I have a box that you can tell was dropped.  That box gives light strikes.  It gets used for practice.  Luckily, the rest of the case is fine.

I had one lot (case) of CCI std that would give me a once out of 100 (just guessing) a fail-to-fire.  After rotating the round 90 degrees three times and trying again, still no fire.   I pulled the bullet to pour out the powder and inspect the case.  The green primer poured out with the black powder.  I have had other issues too.  CCI Std used to be my GO-To-Dependable-To-Fire ammo.  Not so much any more.

The remaining 8+ boxes from the brick are in transit to CCI for examination. 
Every round that fired very weakly was in the box at one end.  The first 14 starting from one end were all weak.  At the middle in the box, half the shots cycled properly.  There were fewer bad round at the last end of the box.  It was not random in the box.  That's a real mystery.  All the rounds did fire on first strike.

I am totally weirded out.  CCI examined the remaining ammo of the brick in question.  Their response:
We received your rounds in our office and had a pressure and velocity test done on a sample of these rounds that resulted with all the rounds meeting print specification. At that point I took the remainder of the rounds and functioned them in a Ruger 10/22 and experienced zero issues. There was nothing wrong with the ammunition that was sent in for testing. With that I am having the ammunition sent in replaced and this should ship in the next 7 to 10 business days based on availability.


I was not imagining the weak cycling ammo.  Five shot strings went like this in order:

String 1.  5 shots CCI, all weak
2.  5 shots Eley Sport (purple) all good
3.  CCI again, all weak
4.  Eley yellow, all good
5.  CCI again, 4 shots all weak.  I did not fire the 5th shot, don't remember why


Next day, continuing end to end of "bad" box CCI
String 6.  3 bad, 2 good (this is the 4th 5 across the box)

7.  same (5th 5 in bad box)

The second half of the "bad" box had fewer weak shots.  Maybe 4 weak, rest good.

And at the same time all shots of other ammo were good.



I guess it will have to remain weird.
