chetc Posted April 8, 2021 Share Posted April 8, 2021 i am getting low on my small pistol primers, i have a few 1000 of small rifle, will they work ok in small pistol use. chet Link to comment Share on other sites More sharing options...
Alaskapopo Posted April 8, 2021 Share Posted April 8, 2021 Yes with a few buts. Work your load up again as the primers are hotter. And they may give you miss fires in Glocks or revolvers with lightened striker springs or hammer springs in da mode mostly in the revolver Link to comment Share on other sites More sharing options...

Also there's a You Tube video by Atlas gun works thoroughly explaining the use of various primers for use in pistol ammo.

pjb45 Posted April 8, 2021 Share Posted April 8, 2021 I have used Federal Small pistol; magnum, match, rifle; magnum and match for 9mm and 40 S&W with VV320 in my Limited and SS guns with no problems. Generally, Zero bullets are used in my guns. Range brass offers a slightly greater variance than once fired (out of my guns) brass. I do have extended firing pins. i do not load to max but rather a 166-169 power factor. I have seen some limited data stating there might be a 10-15 fps increase in velocity by using rifle or magnum primers. I never statistically noticed a difference in over 20,000 reloads. My chrono data does not show much of a difference for me to worry about pressures, that and the primers do not show any pressure problems. For you statisticians I did use a Variance of Means algorithm. I have several boxes of 'control' ammo = ammo used at National and Area matches that was chrono'd and left over. I have not tried the different primers in a revolver yet. Probably next month. CCI has published some very good papers on primers. Link to comment Share on other sites More sharing options...
RGA Posted April 8, 2021 Share Posted April 8, 2021 FWIW, back in the 90's I used CCI400's in 9mm without issues. My loads were not max though. These CCI's are hard but I had no ignition problems in a std Glock and Beretta 92. Large rifle primers though were a different story. The ones I had on hand (not sure anymore if they were CCI or Fed) were too tall for the primer pockets of the brass I had. Link to comment Share on other sites More sharing options...
Guy Neill Posted April 8, 2021 Share Posted April 8, 2021 While small rifle and small pistol primers have the same dimensions, the large pistol and large rifle differ. Large rifle primers are taller than large pistol. Link to comment Share on other sites More sharing options...

adamastergunner Posted April 8, 2021 Share Posted April 8, 2021 In the end it sounds like there is no issue with using small rifle primers in place if small pistol primers. Link to comment Share on other sites More sharing options...

bigdawgbeav Posted April 8, 2021 Share Posted April 8, 2021 I was able to pick up a bunch of SRP's as well. Since all of my pistols are using lighter springs, I'm saving all the SRP loaded rounds for my PCC. Tested CCI and Win SRP and they ran great.

No. If loads are really light sometimes the harder rifle primers do not expand in the case enough to stop harmful gas cutting of the breech face.

IPSCLUVERRR Posted April 8, 2021 Share Posted April 8, 2021 Back in the early open major days almost everyone was using SRP in their guns, it was just something that had to be used. To this day I strictly use SRP in my 1911/2011 pistols. In my lightened p320's/tanfos I have to use small pistol but some of the guns will fire SRP. It won't hurt the gun at all whichever primer you use. And based on the Atlas/Vel ammo primer test there is negligent difference between velocities and pressure.

ltdmstr Posted April 8, 2021 Share Posted April 8, 2021 One of the major manufacturers, think it was Federal, but may have been Winchester, told me probably 20 years ago, that the only difference between the two is the hardness of the cup. The type and quantity, etc. of the priming compound is exactly the same. I doubt anything has changed since. Link to comment Share on other sites More sharing options...

While I have great faith both of you guys knowledge I only know when I did a simple test of just firing a primed case in a dark garage my Fed SRP’s were louder and shot more flame out of the comp and barrel than any SPP I compared with. BUT I do completely agree that in loaded ammo they all performed about the same as far as velocity etc Link to comment Share on other sites More sharing options...

grsdoug Posted May 10, 2021 Share Posted May 10, 2021 " According to Speer/CCI Technical Services - Both the CCI 550 Small Pistol Magnum and CCI 400 Small Rifle primers are identical in size. Both primers use the same cup metal and share the same cup thickness. Both primers use the same primer compound formula and same amount of primer compound."

SGT_Schultz Posted May 10, 2021 Share Posted May 10, 2021 I recently tried some Rem 7 1/2 primers in my usual load (3.8 TG 125 gr conical mixed brass) and couldn't tell the difference in recoil from the same load with CCI SP or with WSPM primers. I'll get around chronoing them one of these days. Link to comment Share on other sites More sharing options...

And I did not have to work up with change my loads at all a small pistol primer has 15 pounds of energy and a small rifle primer has 17 pounds of energy as per guns and ammo testing.
