    CCI primers- just asking for trouble

    a friend of mine who i shoot with a few times a week got a batch of cci primers instead of his usual winchester for one reason or another.
    over 10% of them so far failed. . he is disposing of the rest of them and going back to winchester.
    enough said.

    edit: now that i think about it, it was well over 10%. once there were THREE in one magazine (7 rounds) that went click

    I have found for years - personally and from other's experience ... the primer cups are heavier gauge material and/or harder. More ''oomph'' needed to initiate them. I don't see any problem chemically however - just need a bigger hit.

    If a gun has plenty of 'zap'' in the FP energy then no problem but if marginal then they can be susceptible to a light strike effect.

    I choose Fed and always have tho Win have done me fine too. Fed seem the ''thinnest'' of all. This problem shows up most when a revo it tuned up and lightened main spring - and then plenty of chances for misfires.

    As Chris said if you use CCI you have to have some oomphh anything with a lite trigger job will have a hard time setting them off.. Here awhile ago i had winchesters do the same thing

    I used CCI's until I put lighter springs in my GP100 & SP101; got a lot of misfires due to light strikes with them. Never had that problem with Win. primers.
    I'm a child of the 60's, but I got over it.

    Actually, I just read a thread on another forum, from a guy who just purchased a Lee Auto Prime tool (which I also use), and said it was NOT recommended to use Federal primers in this tool because of the chance of multiple detonation due to soft primers.

    The only problem Ive had with them is picking them out of the receiver after loading too hot.....

    I have been seeing problems with Win primers with my .40 reloads. I have used CCI with few problems. I have seen many more squibs with Win primers. I am shooting a stock HK USP. I have no problem with primer strikes (AFAIK) but with lack of detonation in the primer.

    Glocks are known for hating WLPs. First I've heard them not liking CCI. I run CCI and WLP in my G30 with no issues.

    I've used CCI primers as my primary primer for more than 20 years. If I have a gun that won't set them off it's either because I got a bad batch, because I damaged a batch, or because I damaged the gun.

    They are harder than Win or Federal primers, to be sure. Any gun that can't set off a functional CCI primer has problems, though.

    It isn't so much the softness it's the strength. The Lee Auto Prime won't take the beating of them going off and it will risk injury to the operator.

    Straight from Lee Precision:

    http://www.leeprecision.com/cgi/faq/index.cgi

    Primer Brand Warning

    We recommend only Winchester and CCI primers be used in the Auto Prime because Federal and Remington primers pose a potential danger to the operator. In testing, we found that the latter two brands of primers almost always chain detonated if the primer being seated was accidentally set off. A primer going off near your hand can be compared to an M-80 firecracker.

    When a full tray of primers explode, it does so with enough force to cause injury to the operator and anyone else standing within a ten foot radius.

    The older Improved priming tool and our current production Ram-Prime only accept one primer at a time, so this hazard did not apply.

    We take no position as to the quality of primers and mention this only because of the increased danger of chain detonation with some brands only.
