Has anyone ever substituted small rifle in pistol loads in a rifle.

[jonbearman]

I am in desperate times. I work part time for a gun manufacturer and we are just about out of small pistol. I will start low and work up and the gun is actually a 9mm rifle using ar-15 fire control parts. What do you fellas think.

I think that it would be interesting to test the brisance of the respective primers by using each of them to fire a soft or swaged lead bullet into your bore. (primer only - no powder) This may sound like a crude test, but it would give some idea of the power difference between the two.

I've got a hunch that many of us may be trying component substitutions in the future. jd

As a result of a major 223 and subsequent 9mm loading session, I have about 35 mixed primers of small size. I was planning to use them in 9mm for range training ammo. The load is a mid level with CFEPistol so I’m not too worried about pressures. So, while I would not substitute them generally, in mine and your application it should be ok,

Many reloaders are using small rifle primers with thinner cups for pistol ammunition. The thicker small rifle primers with a cup thickness of .025 might not go "bang" in pistols with weaker hammer springs.

Small Rifle Standard

CCI 400 -thin .020" cup, not recommended for AR15 use by CCI/Speer. Good for .22 Hornet, .30 Carbine. See Note 1 at the bottom of the page

NOTE 1: 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. They can be used interchangeably.

I've been using CCI400 SR primers in my two pistols, a Ruger-57 and a S&W M&P full-size 40S&W for months. I see NO signs of high pressure and have had NO failures to fire. I'm neither looking for, buying, or using any more SP primers.

You're welcome to start low and work up; I didn't after getting lots of advice to not worry about that.

I built a 9mm win mag based wildcat on a AR 15 platform a few years ago. Exactly what uncle ed mentions i experienced they were interchangeable. Another issue i ran into was i had issues with fed sm pistol primers in a ar 15 9mm project suddenly emptying a mag. I switched to small rifle in the end and the problem went away. I now just use small rifle primers for that application with no problems.

Using small rifle primers in relatively high pressure pistol ammo is fine. If you load them on the light side of things, the primer doesent seal the primer pocket all the way. You can get some leakage around the primer pocket and subsequent breech face erosion.

Jon,
I have used them in a 9x23mm Winchester, never an issue. The original load data from Winchester listed SR primers with WAP powder. This is in a Colt 1911. I don't see why there would be an issue, but as always work up and be cautious.

Why would small rifle primers work reliably in a .223 AR rifle, but not work in a 9mm AR rifle?

If the OP works up the load carefully, he’ll be fine.

Here, down under, there have been times when small pistol primers have not been available and small rifle was the norm. As an ISSF pistol shooter, I was even using SR's in a .32 S+W. Just had to adjust the load, maybe by .1 or .2 grains. I don't remember accuracy being affected. Needs must.

 

[Mark Self]

I have been using small rifle primers in my 38 comp and 9 major pistol for 18 years. I have also loaded thousands of them in my Carry Optics 9mm CZ.. ZERO problems!

 

[yotehater]

The lonely Rem 6 1/2's are perfect in 9mm loads.

 

[jonbearman]

I would 6 1/2's but eveything is unoptanium right now and it looks like it will get so bad reloading will end with no more internet sales brought to you by the democrat party. Maybe I should sell all my stuff and just quit.

"Never give up, never surrender."

Have loaded and shot a bajillion 38 Super, 38 SuperComp, and 40 S&W with SR primers. "No problemo."

 

[jonbearman]

I still gotta find primers which is the weakness for a project I am working on for a manufacturing company.I work part time on this.

actually years ago one of the gun rags, Guns and Ammo IIRC did brisiance tests using cutaway cases and highspeed photography it was an interesting read
Some SPM were hotter than SRP

 

[gmorris]

I’m also asking if anyone has tried lr magnum for large rifle primers and should I start with reducing powder loads and if so how much?

Have a friend who used small rifle primers in his pistol cartridges. Says he didn't notice any difference. Of course you cant get small rifle primers any longer.
