CCI #400 srp substitute for SSP

For some loads I use SRP instead of SPP. I have never used SPP instead of SRP for rifle though.

The sticky Reloading Library of Wisdom here at THR includes a thread discrediting that premise.

Here's a lesson in facts. Instead of posting or believing old crap about technical information that might or might not be true, contact the manufacturer directly.

Only the manufacturer can provide the facts on their products. Don't trust some yahoo on a forum. Forums are notoriously riddled with BS. If you have a technical question about a product, ask the manufacturer.

In the case of CCI primers or products, you can use this link to ask them directly: https://www.cci-ammunition.com/contactus

That's what customer service is for. Ask them.

Because of all the rumors on forums, I asked CCI directly if their 550 and 400 primers were the same. They said they were not. But don't take my word for it, ask them yourself. https://www.cci-ammunition.com/contactus

Correct, you can buy the right primer for the job or do your own research from the manufacturer.

My experiences with putting SRP into pistol loads is that my guns had several light strike per 100. These weren't with CCI 400 but with Wolf SRP that were specifically recommended against being used for the AR platform due to softness. The gun had all stock springs and never had light strikes with any pistol primers.

The best way is to try 100 and find out if your gun will ignite them.

The reason he is asking is because he can't buy those primers.

You left out “or do your own research...” changes advice entirely, no?

Sure, if buying the right primers for the job is an option right now.

(It is probably not)

Speer's a good manufacturer to be contacted about bullets too. They can explain with more detail than is in their advertising material about how the Speer Gold Dot Jacketed Hollow Point bullets and Total Metal Jacket bullets are indeed jacketed bullets and the difference with the plated bullets Speer manufactures to compete in the plated bullet market.

If only people would contact the manufacturer each & every time!

One of my 38s gets light strikes with CCI pistol primers.
SRP would make it a good brick.

OP give it a try and load a few. AS always start low and work up your charges. I picked a new 686 a few months ago and had no SPPs because I never needed any. I have plenty of SRPs and they run both 38s and 357 just fine. NO light strikes, no flat primers and accurate. YMMV... In these times one might need to learn I A O and carry on...

Contacting the manufacturer is all well and good as they should be able to give you accurate information about their products, but IMO nothing beats my own testing to determine what will or will not work in my guns.

I know which SRP's will fire and which ones will not fire in my guns through testing. That trumps even manufacturer info in my book.

The above is solid advice.

And remember...

1. There is no known safety risk in doing what you are asking about.

2. It is commonly done enough that you can get several people to give you their input on the subject.

I'm not saying don't contact the manufacturer, but if they say "rifle primers are for rifle cartridges and pistol primers are for pistol cartridges, thank you for calling" then you are right back where you started.

Ugh I have 3 diff SRP's and the SPP's I cannot use for 40s+W as per Remington only the 9mm....I'm so wanting to load some 40 rounds...I have read others do.. Bu tI'm a noob.

Or we can do a little research and draw some conclusions based on information.

For example, I recently began loading the .30 Carbine cartridge. Being a rifle cartridge, I just assumed I needed to use a small rifle primer. But then one day while I was charging a .30 Carbine case with 15 grs. of H110, it occurred to me that my .357 Magnum hunting loads use a heavier charge of the same powder, but I use a small pistol primer in the .357. Then I remembered reading a couple of articles by Brian Pearce on loading the 32 WCF (Is it a rifle cartridge, or is it a pistol cartridge??) in Rifle and Handloader magazine in which he used a variety of primers. So I tried in the .30 Carbine, with the same powder charge, SR, SRM, SP and SPM primers in Fiocchi, Wolf and CCI. The bottom line is, there really wasn't enough difference in velocities to spit at, which of course means there wasn't enough difference in pressure to spit at. Certainly there were no spikes in velocity.

Think about it: Why would rifle cartridges such as the .22 Hornet, 218 Bee, 25-20, et al, use small rifle primers, and cartridges such as the .357 Magnum, which use more powder, use a pistol primer?

I'm not suggesting the use of SRP's in a .357 in the place of SPP's, but if the latter were all I had, I'd use them.

Here's a lesson in paying attention:

My reply was specifically directed to the post saying that CCI 550 and 400 primers are the same primer.

Feel free to read it again.

It does not mention/address the question of whether one can use rifle primers in a handgun. That's a completely different question.

Lots of lessons being given here

Part of your post related to 550 vs. 400, the rest was general chastising.

I was responding to the first part of your post and merely offering my experiences obtained from reading and chronographing, the latter of which is ironically, fact.
