Someone told me that I could use small rifle primers in my pistol cartridges, but not the other way around.

I reload for 223 and 357sig in small pistol. I'd like to be able to buy one type of primer in bulk, WSP for 223 - and still be able to use them for my pistol reloading.

Has anyone input or sage advice? Have you done it, did it work... Will I BLOW UP?

Thanks:o

Ummmm, I used some small pistol primers in my small rifle. I had some pierced primers, so I used small rifle primers after that.

Blow up unlikely!! You will tho find ... dependant on guns used, that inconsistent ignition might result.

The thickness of primer metal is significantly greater ... a ''stronger'' primer if you like ... to take higher pressures .... that can lead to effect like a light strike when springs derated.

Best quite frankly to use the real deal. I have always found in pistol primers - that CCI are about the hardest ... with Fed's being about softest .... if a gun is ''fussy''.

Certainly ... DO NOT use pistol primers in rifle cartridges .... look at the proof pressure for, say, a Mini-14 ..... 17.5 tons! That lil case has quite some pressure peak!

There are exceptions to the pistol primer in a rifle case. I load 22 Hornet with small pistol primers, but the Hornet case is no larger than most pistol rounds. I was concerned about pierced primers but have not experienced any.

Yes, SRP fits where the Small Pistol primer fits. Lots of 40 S&W and 9x23 shooters and us crazy T/C contender nuts do it all the time. It is to help with "primer-flow" problems. Don't do it unless you know what your doing!

It works fine unless you have a very weak mainspring as for a very light DA revolver setup. I am loading 9mm with small rifle primers that I got from an estate sale after a local shooter passed away. I went back to the starting load and chronographed and adjusted until I got back to factory equivalent. With my loads- HS6 in 9mm- small rifle primers did not boost the velocity much at all; but small pistol Magnum primers increased it a good deal.

Federal used to recommend their small rifle primers for .357 Mag before they came out with small pistol magnum primers.

I would not load rifle or Contender ammo with pistol primers. Some black powder shooters do, but that is a very special application at low pressure.

Large rifle primers are taller than large pistol and should not be substituted, they lead to high primers which can be big trouble.

I have used SRP in my 40 for USPSA for a while. THe problem is that since the metal is harder it takes more to seal the primer. I have had a few rounds that the primer didnt seal and they fealt real light. If small pitols primers are working then I wouldnt change. If you are getting primer flow then you could switch. If the load isnt very hot though you might experience the same problem I did. Watch out for it if you do.

Primer flow problems ?? You obviously are loading well over maximum pressures.

I've used small rifle primers in all of my pistol loads for years. They're a little harder than pistol primers, otherwise no difference.

Don't use small pistol primers in your rifle loads though.

I use CCI 400s in all 9mm, 357 SIG, and 357 Mag "HOT LOADS".
