CCI Primers?

[brbanks1]

Good Evening my fellow CZers, I have a quick question..

I have a Shadow custom tuned by Stuart and I have a lot of CCI small pistol primers on the bench, do you guys have any experience loading CCI primers with the lighter mainspring installed?

Thanks in advance for the help!!

I found the CCI's easier to set off than Winchesters. Using a Glock with 4 # striker spring and stock striker. This was a surprise to me!

Don't know if this helps but

I use cci small rifle primers and have never had a ftf running a 15lb hammer spring

[The Antichrome]

My Shadow has a 13lb hammer spring.

I use only CCI primers with no issues.

[Philo_Beddoe]

I have two shadows both with extended firing pins and reduced power firing pin springs. One will only ignite cci small pistol primers at 100% with a 15 lb hammer spring, the other will do it a 13lb hammer spring. I have cleaned the firing pin channel on both.

Which mainspring do you have installed? Do you have the extended firing pin? Stuart offers different trigger jobs. My Shadow will reliably light off even CCI primers with Stuart's "Federal only" trigger job. This one uses the CGW 11.5lb mainspring. Your best bet is to try it out and see what your gun can do. Make sure you seat the primers as deeply as possible.

Bingo. I have found that sometimes people having light strikes are inducing them by not seating the primers properly. If you are using a progressive press, make sure your priming ram is set up for maximum primer seating depth. My shadow got through its first match Sunday igniting cci primers with an extended fp and reduced-power fp spring. No issues.

My TS runs CCIs fine.

Per the specs from the cz custom site, My shadow custom was shipped with a 13lb mainspring.

I use TULA small pistol primers for around 600++ rounds zero ignition issues.

Worked fine on my CZ.

Stuart worked my CZ75 SP01 along with Matt Mint. I just finished 10-15k of CCI SR primers (bought what was available at the time) and had absolutely no issues (unlike Wolfe SR & SP primers). I did leave the extended firing pin in the pistol after the Wolfe primers were gone. Primarily because of the statements about how "hard" CCI primers are. Now shooting CCI SP and no issues. 13lb main spring BTW. Will most likely go back to the standard length FP. Did order the CGWs tuner package of RSs and their 12 lb. main spring. Have not arrive yet.

No issues at all with mine and I've ONLY used CCI primers.

I've had a problem with the lighter hammer spring and CCI primers in my Shadow. Unfortunately I don't know exactly the hammer spring weight factor, but I do know that ever since I've switched to Federal I've never had a problem. I also find that the Federal primers are easier to insert into the case, at least with my Hornady LNL.

The softer cup on the Federals definitely makes a BIG difference in both areas.

13# spring here. No problems lighting CCI SPM's or SP's by Win, Fed or even Wolfs.

Update. CGWs parts arrived. Tried the 11.5 lb hammer spring. Dropped DA pull 10 oz. 13 lb spring had a DA pull of 7 lbs. 12 oz. 11.5 lb spring DA was 7 lb. 2 oz. I would say a very good and positive change, but I do need to tweak the trigger return spring slightly. I expect a DA pull to be below 5 lbs. after that. SA pull was no change. Fired ~240 rnds. using CCI SP primers and no issues. Changed to the 8.5 lb hammer spring. DA dropped to 5 lbs. 2 oz. SA no change. Experienced 3 misfires. I increased the primer seating depth .001-.002" and have now shot ~350 rnds. with no issue.

The 8.5 lb. springs has a soft, smooth pull. I like it very much and will stay with this hammer spring.

I installed an Angus extended firing pin when using Wolf primers a couple of years ago and will leave it in for now.

I think this combination is a WINNER!

Will check and see if there are issues with softer primers using the extended firing pin. CJWs says they only guarantee the 8.5 lb. spring when used with Federal primers.

Next step is to see if recoil springs change anything for the positive for me.

Remember YMMV and test everything.

Used a 13 lb. hammer springs until last week. ~50k rnds through the pistol and on the only primers that caused me issues were Wolf. Initially using OEM firing pin. Changed to Angus' extended firing pin. Things improved but did not completely go away with the Wolf primers. Winchester & CCI SR & SP always went bang with that hammer spring. I am 100% positive that Remington and Federal would always fire too.

I shoot 147GR ATL Arms Black Box. Normally Danny uses Federal primers with Starlite Brass. However, lately he has had problems getting the Federal primers and is loading the CCI primers, not sure which brass. In any case, I shot all weekend at a match and experienced no light primer strikes on the CCI primers.

[blsexton]

I have to go up 1 spring weight in the main for using CCIs vs Federals. Using CZ75b

[highxj]

I have a P-01 with extended firing pin, reduced FP spring, and CGW 11.5 lb. main. I normally run a 13 lb main in this pistol as it's more defense oriented but stuck in the 11.5 as a test. I just ran 100 rounds through it with CCI SP primers loaded on my Hornady LnL, which only seats the primers flush at best. No light strikes, and that's with about half of them shot DA.
