dlightning Posted June 22, 2019 Share Posted June 22, 2019 Hey everyone, I need some help. How can I tell the difference between CCI small pistol primer and CCI small rifle primer? I was getting ready to reload some 9mm for PCC. (3.1 gr Alliant Sport Pistol, 124 gr Gallant, CCI small pistol primer). I found one of six primer reloading tube full of primer. I believe it should be from the last reloading session which was months ago of 223 using small rifle primers. But I want to be sure. Any suggestions? I've tried visually comparing but can't tell any difference. Quote Link to comment Share on other sites More sharing options...
George16 Posted June 22, 2019 Share Posted June 22, 2019 Visually, theres no discernible difference between the two. I had used both CCI small rifle and pistol primers on my MPX using 4.0 Gr of Sport Pistol and 124 Gr PD JHP @ 1.125-1.128 OAL” without any problems. I can’t even tell the difference when I was shooting my reloads. Brass were sorted by head stamp too. Quote Link to comment Share on other sites More sharing options...
herky Posted June 22, 2019 Share Posted June 22, 2019 Agree that either should be no problem. Some primer compounds are a different color depending on SSP or SSR, Winchester for example. Quote Link to comment Share on other sites More sharing options...
Ken6PPC Posted June 22, 2019 Share Posted June 22, 2019 I have compared loads using SP and SR CCI primers, and the results were pretty much the same. However, if you have lightened the trigger pull by reducing the hammer spring, you might have problems igniting the SR primers. CCI primers are harder to ignite than say, Federal primers anyway.

dlightning Posted June 22, 2019 Author Share Posted June 22, 2019 Thank you to all. I'll give a go. It is going out of a 14.5" pin and welded so I'll measure the velocity to see. Thanks again Quote Link to comment Share on other sites More sharing options...

Guy Neill Posted June 28, 2019 Share Posted June 28, 2019 Balletically the cci small pistol primers and small rifle primers should be very similar. The main difference is the thickness of the cup. Quote Link to comment Share on other sites More sharing options...
