CCI No. 41 Primers (Small rifle)

With the scarcity of primers, has anyone used these primers in small pistol cases. Results?

I have read over on Brian Enos' reloading forum that 9mm major shooters run SRPs in their open guns to deal with the higher pressure generated by the high power factor. Expect them to be harder to light.

I've done it, but only on a small scale to test the theory when I first read about it on this Forum several years ago. SPP's & SRP's are pretty much interchangeable in common handgun calibers, as long as you're at mid-range or lower loads. May be OK at max loads but I don't know and am not adventurous enough, nor care enough, to test.

I have used SR primers in 38 Super all the time with no problem.

BUT, these #41 primers were designed for 5.56 rounds that are used in AR's or M16's with floating firing pins, I wonder if they are extra thick !

I guess the only way to find out is to load a few of them.

I only have the CCI 400s SR primers, but they go bang just fine (in my CZ 75, anyway).



I'm planning on loading up a few soon and chronoing the same load using SP and SR primers

It will be interesting to see.

I have the opposite issue

I was going to post a WTT ad, offering up SPP's in trade for SRP's...

If anyone is near (or was going to be going up or down I-35 through) the Temple/Belton area in the near term, we could swap some.

Yes, BUT they are hard cup magnum primers and may be more valuable for trading.

Yes, BUT they are hard cup - extra thick as mentioned above - magnum primers and may be more valuable for trading to AR and such users who have few alternatives.

There are many alternatives for handguns in general.

I have and routinely use small rifle primers in assorted 9x23 loads. That's my only experience.

I would not hesitate to use them in plinking loads in other cartridges. I would hesitate to use them in other than plinking loads. I have no doubt appropriate higher performance loads exist but they aren't in my books and I don't need to setout for unknown realms so I don't.

With low pressure ammo you might get some leaking around the edges of the primer because the primers are harder and they dont seal the pocket as well.

After a little while you can end up with some breechface wear/errosion that matches the outside of a primer.

High pressure ammo seals them up just fine.

You can use small rifle primers in lieu of small pistol primers. As always start low and work up.

However I would be reluctant to use the #41 as it has a MUCH harder cup.

It will be interesting to hear.
I have 9mm samples loaded with Fed SR, Win SR, CCI BR, and CCI SP Mag for trial.
I don't expect any failures, I used SR primers in 9mm during an Obama panic with no problems, but want to reassure myself before I need them for a match.
(On the other hand, I did not get satisfactory ignition from Rem SP or Wolf SP. Obviously they work in other people's guns; just not mine.)

Been living right, I guess. I met a BR shooter today who has retired and is slowing down... he was kind enough to dip into his SRP stash to help me out!!

As others have said #41 primers are 5.56 NATO spec to resist slam firing in an M16/M4. I would be hesitant to use them in a pistol load.

The boxes I have say right on them "For 5.56 Ammunition" "Small Rifle Military Primers"

Found this on Brian Enid forum, thought it might help shed some light.

Yeah, I'd bet that some hammer fired CZ's and 1911's (well, 1911's have a floating firing pin outside of the 80 series and some other abortions) might be able to bust a #41 cap but Glocks, other striker fired pistols and of course tuned revolvers are going to be questionable at best-in fact as gawdawful as the trigger in an untuned SP-101 is I'm not sure they would set one off.

Even with the ordinary small rifle primers I will be using in the current shortage, I will mark them for hammer fired autos, saving the remaining WW small pistol primers for striker guns, and Federal small (and large) pistol for revolver.
