Troubles with CCI-SV?

Post by Mike38 on 4/16/2017, 11:48 am

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.

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 shoot a Benelli as well and have not had failures with it, but I also shoot free pistol and that machine has failed to chamber some CCI and Eley 100’s.  The rounds are so oversized they cannot be pushed into the single shot’s chamber by hand; and about 4 out of 50 that do chamber will not fire unless I eject and reinsert them in a different position.  It is almost like the rim is not completely primed if that is possible.  Simply re-cocking the pistol (in effect allowing the firing pin to come down on the same spot) does not work, but rotating the round so the pin hits a different place works 100% of the time.  While I have a very tight chamber I don’t believe it is the problem.

My Benelli needs to be very clean to keep running well.  In fact I keep a tooth brush on the table and between clips will give the breech face a quick brush.

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.

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