Troubles with CCI-SV?

Is anyone having troubles with CCI Standard Velocity .22LR? I'm getting about 1% failure to fire, but always work the second strike. 1% is a lot as compared to years past, that's why I ask. I might have to switch to Green Tag for matches and use SV for training. Then again, maybe I just got a less than perfect lot and it will all go away when this half case is gone.

What pistol are you shooting?

I would mention that if it fires on second strike and your not changing the position of the case in the barrel then you might not be getting a strong enough firing pin strike. It sounds like there is primer under the rim of the case.

Pistol is a Benelli MP95. Has two firing pins, one is 0.001 longer, and that's the one in it. Fires on second strike after rotating cartridge. I guess it could be dirty chamber not letting cartridge to go fully in. I will check that. So I've been told the chamber needs to be very clean on these pistols. True?

I am almost through a 500 count of CCI-SV.
No issues with two different pistols.

I seriously doubt the Benelli mainspring is too light. Do you use a dental pick or something similar to clean breech face? I commonly see dirty breech faces that are contributers to light striking. I have also seen some lots of cci misfire.

Some of mine have a bulge at the case mouth that keeps the round from fully chambering . Almost like to much crimp.

My micrometer shows a larger than normal diameter then the body of the rounds. But the bulge is  right at maximum diameter,  when compared to SAAMI. 

Shooting a vintage 70's High Standard thats never been a problem before.

the only ammo my high standard trophy don't friendly was a batch of Blazers,because overize brass in the camber don't permit the ejection. but out of this,shoot any ammo without problem.

My chamber must be clean, or clean enough. I did a "plunk test" with around 20 CCI-SV rounds and all fell in fully and fell out fine. I went ahead and brushed the chamber anyhow. Curiously enough, Eley Practice 100 failed the plunk test, even after brushing the chamber, but I've never had a failure to fire with Eley. I may have gotten a bad lot of CCI. Luckly I only have 1000 rounds or so of it left. Prior to this batch of CCI-SV, I do not recall ever having problems with it.

I also have a Benelli MP95E.  If you've shot several thousand rounds through it, then it's a good idea to replace the firing pin , recoil spring and the mainspring.  Seems to solve a lot of problems.  Also the chamber must be super clean.  Larry's Guns suggests using a .243/.25 rifle bore brush, bend it into an L shape and scrub the hell out of the chamber with Hoppe's or whatever good bore solvent you like. It will make a difference.  I found out the hard way, not realizing the need to thoroughly clean the chamber.  

As for the ammo, It's rare to get a CCI to not ignite, but light strikes can happen.  My failure rate with CCI SV is very low, maybe 1 in 1000-1500.

That matches my experience as well.  With our Junior Pistol group, we go through about 750 - 850 rounds each session.  When we were using Rem Thunderbolts, we had 4+ duds per session.  After switching to Aguila (HV, not the SV or match stuff), it was much better, and we were only getting 2-3 duds per session.  After switching to CCI SV (combination of my urging and the recent price drops), the failure rate has again dropped noticeably.  I only recall 1 dud in each of the last two sessions.  These are not always the cleanest, most well-maintained guns, and poor user technique is common, so you need to take our failure rates with a grain of salt, but the choice of ammo makes a noticeable difference, and CCI SV has been pretty good to us so far.

I've had good success with SV but with some other ammo when I found a dud I removed the bullet and powder to find there was no priming compound where the firing pin hit.  This explained why the round fired after rotating it.

I noticed this thread and wanted to add to it. I have been reloading 38 spl target loads with CCI small pistol primers and getting quite a few misfires. The primer strike is a solid hit but they do not ignite, but some will upon firing them a second time. I started checking the primer seating depth and they are all the same. I called CCI and the guy said they have had no other complaints so it musy be  the seating depth or my gun. He just blew me off in a nice way.

What gun are you using for these? I have this issue with my revolver due to lightened springs but did not have issues when the gun was stock.

If you have the factory 10# DA trigger pull you shouldn't have an issue. if its now 6-7# DA you need to switch to Federals.

I am shooting a S&W model 19 with hand loaded 38 target loads

The only failure to fire I have ever had are from dirty chamber face or breach face. Dental pick fixed that real quick
