Small Rifle Primers

[jellyb]

Are there any negatives with running SRP's in PCC's?

TIA

[Boomstick303]

No.

[usmc1974]

I use srp and lrp for everything. Just saying 

[jerseyglock]

I've been using Wolf small rifle (.223) for past many many years, they go bang!

[WarLeg]

what loads are y'all running when using SRP? thinking of using these as a temp replacement for SPP's.

[OPENB]

All the rifle triggers I've run across will reliably ignite rifle primers loaded in pistol cases. Should be GTG. A very good way to conserve pistol primers for lightly sprung pistols.

Start with your regular load and see how it works.

If you're already on the "hot" side with your load then start a little lighter and work back up, but I haven't noticed a difference.

[usmc1974]

I am not changing my loads. If I remember right it was over thirty years ago that guns and ammo did a study. SRP had 17 pounds of energy and SPP's had 12 to 15. Magnum SRP's had about 19. I have found SRP give a very nice even ignition in my pistol loads.

thank you everyone for your responses, greatly appreciated.

Somewhere on this forum there was a rest of SPP vs SRP in terms of velocity and PF.  If I remember correctly there was no appreciable difference between the two.  SRPs usually have a harder cup so may not work in a pistol with lighter springs.  Some of the PCC manufacturers actually recommend using the SRPs 

[jellyb]

Awesome share folks!! Thanks for the responses!

So far all of my pistols run well with SRP.

Once primer prices return to somewhat of a normal price, all I will stock is SRP and no SPP.

[BiggMike]

No problems at all.

Same here, but I am running low on LRP got less then 10k

Run srp in my .38 super and sti .40 since day one.  Use them in the pcc also.  Chrono them with the pcc against spp....had less than 4fps difference, much to my surprise.

[cperazza]

Nope.  Running SRP on my PCC, Limited and Open guns with no issues. 

 

Note: If you use mag SRP you might see a spike (15-20 fps) in velocity, that you might have to adjust on powder charge. 

[Squirrel45]

Like everyone else said no issues. However my pcc doesn't lite #41s to well. Those are mil spec 5.56 caps

I tried S&B SRP I did have a issue with these in my glock 19 gen t5. This is the only time I tried them. They did run fine in my JP GMR 15.

To the people espousing the interchangeability of LRP and LPP's, please be advised that there is a dimensional difference between those two that doesn't exist with the SPP/SRP swap:

Primers are starting to be available again but at a very high cost.  Target Sports shows Remington, CCI and Federal small rifle and small pistol primers in stock but at $600/ case of 5000!  It does include free shipping so that's something.

[bigdawgbeav]

so small rifle magnum would probably OK if using already a light Steel Challenge load?  Have a line on some Remington 7 1/2 Bench Rest primers that (from my understanding) are just small rifle magnums...

I know all are saying no problem. Like everyone I got some CCI SRP when things got tough. Tried them in 2 of our PCC's running Taccom Bolts & FP. They worked fine. Tried them in an older BCG that I can't remember where I got, but have had it for years and they were inconsistent. Some lit off every once in awhile they wouldn't fire. Could be worn FP & spring. My advice is to try them in practice.

It could just be high primers.

Not high primers. They run in our other PCC's and have never run in consistently in this one.  Why would you not check a batch of ammo when you change components before running them in a match. Not a good time to find out if they work.

 

Between the 3 of us shooting we have several 9mm STI's that run SRP with no problems, but our Cajunized CZ's will not run them.

Maybe you want to seat primers a little deeper.
