Just a simple question....

Is there a way to tell the difference in small pistol and small rifle primers once they are on the loose.
 
No, not really.

If you still have some of each in the original packing flats, the laqure sealer color may be different.

Other then that, there is no way to tell them apart that I ever heard of.

When in doubt, use em as small pistol and back off charge a tad if you are at max loading. Know you may have the chance of a light strike if using a srp in a pistol. Ive never had a problem with a variety of handguns and srp.

My one complaint on cci primers is that they dont color code primers. I cant see a difference between spp and srp. Ill be glad once i get through my last 3k cci spp and move onto my stash of brass colored primers.
 
In the event that CCI500 small pistol primers get mixed with CCI450 small rifle magnum primers, you can sort them out by weight.

CCI500s ~3.3gr
CCI450s ~3.7gr
 
If they are mixed to the point where you don't know if they are small pistol or small rifle primers, treat them as small pistol primers. They are not as "hot" as a small pistol magnum primer and, worst case scenario, they will not work all the time in a striker-fired pistol. I use them all the time in revolvers and have not had a FTF yet.

Small pistol mag is the same as small rifle CCI, FWIW.

They are not the same. This came up recently and to make absolutely sure I called and also emailed CCI. Anyone can feel free to do the same. Here is the simple email response:
Ronald, these are not the same exact primer and you should never mix reloading components.

The gentleman on the phone said the same thing and was very to the point. I have no clue where this thinking came from but it is not correct. The cake mix is different as well as other differences. Again, feel free to email and or call the nice people at CCI if anyone doubts this.

OP is short on details of the actual situation. If I had a bunch of small primers, and didn't know what they were, I would use them for non-critical medium to light pistol plinking loads as it would be safe, and worst case would be some of them might not get struck hard enough to fire from a revolver.
 
TimSr, I left a small quantity of primers in my strip loader and don't remember if I was loading pistol or rifle the last time I used it. In a case like this, I usually let my grandson hit them with a hammer on an anvil.... makes a great little pop with no apparent safety issue. (I also let him ride his bicycle without a helmet and drink from the garden hose). Just wondered it there was a good way to tell the difference. From the answers here, in the future, if it happens again, I'll use them for pistol.

Thanks all for the responses.

Flying shrapnel (anvils/pieces of the cup) would be the most common issue. Primers are very powerful. Y'all be careful out there. :)

Per RC, if you have marked remaining primers you can look at the sealant or compound up close with some magnification. The sealant and or cake color may be different, for example:
CCI-400-CCI-500-A.png

Notice how if we look close under some magnification the inside coloring is different. That may tell you what you have.

Uhhh, surely that was a joke. I guess. Right?

No "apparent" safety issue...ahh the jokes I want to crack here. I shall refrain

I was wondering about using small rifle primers in 9mm a while ago, have some SRP I have no use for.

You'll get a few more fps with the rifle primers. It wont hurt anything other than you MIGHT get some misfires.

It's all in the cartoons. :)

Sometimes it's true that a picture saves a thousand words. All I did was took what RC focused on and gave a picture of it.

Thanks
Ron
