CCI primers
Has anyone experienced lite strikes using CCI Magnum Small Pistol primers(550)? I have one gun that doesn't do well with these. Thanks Dave

If you have worn firing pin springs or a reduced effort spring kit installed you want to use Federal Brand Primers for reloading or Federal Brand Ammo in that gun as they in my experience are the softest primer cups or most sensitive primer compounds and go off 100%.

I have used many CCI primers with no problems.

What is your gun?Has it been modified?How many rounds fired?What is the % of misses?Primers well seated in or any other indication that you've observed that is different from previous experience?

My semi-autos set off CCI primers, but revolvers in DA won't. A rev in SA will (longer hammer travel).
WW primers will work in my revs in DA.
As stated by Sargeyork, Federal primers are the softest; therefore, the most reliable.

I have found CCI SPPs hard to fully seat. Make sure your primers are fully seated to the bottom of the pocket.

I've had light strikes in my Ruger GP100 with the magnum primers as well as the CCI 500 small pistol primers. It happens about 1 in 100 rounds. This is with the factory hammer spring.

I have been using CCI primers and others for decades. CCI in some brass do seem to require a slight more effort to seat correctly. I have not had and problems with FTF so long as I seated correctly and keep the strain screw all the way in. Had some problems with two 686's when the strain screws backed out on their own with all brands of primers. My revolvers are all stock factory springs.
Long story short is no, CCI has given me no problems that were not my fault or backed out strain screw.

Only problem I ever had was with a Tanfoglio TZ-75 9mm (CZ-75 clone) that gave light strikes maybe 25%, factory or handloads. That turned out to be a prob. w/the gun, not the primers. CCI 500s have done the job for me in .38, .357, .38 ACP & Super, and most 9mm, not to mention several calibers using Large Rifle. Been loading since about 1963, had maybe, MAYBE 5 duds/mis-strikes in all that time, except for the TZ.

Hard Primers
The information I gleaned from somewhere on the internet indicates that CCI primers are harder than Federal, Remington and Winchester primers with Magtech and RWS being harder than CCI.
My suggestion is to switch to Federal. If the problem goes away, then it's a primer issue. In my opinion, striker-fired pistols such as the Glock or the M&P do not deliver as much energy to the primer as a traditional hammer-fired pistol. For this reason, I'm using up my stores of CCI primers, all without incident except for a Marlin 336 chambered in .35 Rem.
I bought several thousand Wolf primers on sale and, so far, I haven't had a single issue with them. However, I'm not a competition shooter, nor do I use reloads for SD.

I load CCI primers in my 44 mag rounds. With my Ruger Redhawk in DA I do have light primer marks with misfires. My S&W 629 does not do this.

Just wondering, would there be any less force of the hammer in DA versus SA? I wouldn't think so, but then I've never measured. I ask, because I do own a Ruger Black Hawk 44 mag (SA only). I've used both CCI & Winchester for reloads. Never a misfire.

DA hammerfall is a bit shorter than SA in S&W revolvers and therefore the primer is hit with less force. The hammer force in a Blackhawk is equivalent to a barn door slamming.

There are times when the extra hardness of the CCI primer cup is a desirable feature. I have a .22 Rem Jet that has a larger hole thru the hammer bushing than normal. If I use a soft primer and load a little heavy I have gotten primer metal flow into that hole thereby seizing up the cylinder. So, I use CCI primers to eliminate that possibility. I have had no failures to ignite the harder primer. ....

To me I rate CCI the best. I shoot a lot. Rifle-auto-wheel.gun. I grab the closest one. Tula & Wolf are harder to seat. If there was a primer problem someone in my crowd would have said something. I use them all.

I have a Dan Wesson model 15-2 and it had a "reduced power" mainspring installed when I purchased it. Note, that "reduced power" mainspring produced DA trigger weight of 11.5 lbs. and in Double Action with CCI 500 primers the failure rate was 40% and with the 550 primers it was 100%. However in Single Action both times of primers worked fine, probably due to the rather long hammer fall on the Dan Wesson. Conclusion is rather obvious, the the CCI Magnum primers are indeed harder than the standard pressure primers.
Based on my experience with using Remington UMC ammunition to obtain fresh cases for reloading I believe that the UMC primers (45 ACP, and 10mm/40S&W, ) are equal to the CCI 550 primers in "hardness". Because I've had to re-tune my 610 and 625 to a DA trigger pull of 9.0 lbs. per my Lyman Digital trigger gage which matches to the weight I have my 19-3 and 620 tuned to. I'll also note that I purchased a new mainspring for my Dan Wesson and it now functions with 100% reliability and due to it's estimated 14 lbs. DA trigger I really did not notice any effect on accuracy in re-tuning my S&W revolvers from 8 to 9 lbs. DA triggers.
PS, I have some Federal primers that were purchased "just in case" but I am not a fan of the Shoe Boxes Federal uses to package their primers. My preferred primers is CCI because they take up so much less space than those shipping crates Federal uses. I would much rather increase the trigger pull by a small amount than have to bother with renting a warehouse to store 5 or 10 K of Federal primers. Yeah, I am exaggerating a bit, but it is only by a bit. You can pack almost 5000 CCI primers into the space occupied by just 1000 Federal primers.

I have been meaning to thank you for a comment you made on a gun part I posted a long while back. It netted me an extra $125. So thanks & Merry Christmas. You never know how you can help people.

Other than two duds from the same pack many years ago, I've never had a problem with CCI (or any brand) primers in any firearm--rifle, shotgun, pistol, revolver--make or model.
My opinion is you have a firearm problem, not a primer problem.

Except for the foreign stuff, I've used all brands since 1965. They're all good and the differences are far less than some would imagine.

I have an assortment of primers. CCI is the hardest to seat (probably because they are the hardest) but work in all my revolvers and autos. Winchester is a pretty easy primer to seat and seems to work in everything for me. Federals are the softest and what 45 acp revolver shooters prefer.

Ditto, same experience, with same gun, with about the same frequency, but only DA.

I get light strikes using CCI primers in my M&P Shield 9mm only. No problems in all my other guns. Don't know if it is a primer problem or an issue with the gun. Have about 500-600 rounds through it. Will pick up some Federal primers and try them.

I never replace my mainsprings, and have never had a problem with any brand of primer. I load numerous calibers, both pistol and rifle, and in pistol can not tell via target or chrono what brand of primers I am using. In my rifles, I do prefer Federal 205M and 210M bench rest primers for accuracy.

No and that's the first brand of primers I used and still do. I used a few hundred thousand of them with two FTF. Try a different brand Federal seem to work for my friends. And old bird I got all my cast bullets from only used Winchester.

I recently picked up a S&W model 60 and i'm experiencing light strikes on my CCI-primered reloads with about a 60% FTF rate in DA (they always fire on the second strike). Haven't tried SA as my M60 has a bobbed hammer so not easy to do SA. No problem with factory loads, and my CCI-primered reloads work fine in my Model 10's, so seems to be a combination of CCI primers and my M60 not getting along.

Primers
Yes the Federal primer packaging does seem a little excessive but as long as their primers sell at reasonable prices near that of the other brands I say no harm no foul.
Reloaders remember you are ACTIVATING the primer when you seat it into the brass by pressing the anvil to its correct and most sensitive seating position and pressure without crushing the primer or not seating it deep enough which will also cause ignition problems.

I put a Wolf spring kit in my 686 and have had no issues with any factory ammo or my reloads with Federal, Winchester or CCI primers though Federal is the primary one that I use.

I tried that same kit in my 620, and pulled that mainspring out after its first range trip. It could not fire 550's.

I've had it in for close to two years I guess and like I said no issues. It made a big difference in double action and single action is really nice.

Just to update this story...loaded up some .38 with Federal primers and they fire just fine in my Model 60, so looks like CCI primers were my problem.
