I was given a brick of "Small rifle primers - Magnum" No. 450. What are these used/designed for? Can they be used in a "Small pistol - Magnum"?
What rifle is a Magnum?

If your gun will fire them Proceed. The primers are the same height. Lp. and LR are different. Good video here on pressures. Proving they are safe to use.
Are Small Pistol Magnum & Small Rifle Primers Safe in 9mm?
Today we test 3 popular types of primers in 9mm ammunition. We pressure test and chronograph the 3 to show the differences, if any. If you have questions ple...www.youtube.com
Yep.. i have a brick of the CCI FRP Mag No 450. Wondering what i canuse these for. I really want to use in my .357 handguns.I used these in my S&W M28, 357 mag. No problens.
My pistol eats srp no problem. My carbine with tuned trigger hates them. Never tried mag srp in a pistol.Yep.. i have a brick of the CCI FRP Mag No 450. Wondering what i canuse these for. I really want to use in my .357 handguns.
You have used a MAGNUM primer in a 9mm or 40S&W?I have used them successfully in .327 .357 9mm .40s&w and 7.62x38r. I had a bunch and no spp my guns ran fine but your's may not. Test before you crank out 1k.
This has been done by many people (including myself) with good success. The only issues are as have already been mentioned: cup thickness and firing pin geometry.Yep.. i have a brick of the CCI FRP Mag No 450. Wondering what i canuse these for. I really want to use in my .357 handguns.

CCI Small Pistol Magnum and CCI Small Rifle are the same primers just packaged in different boxes.
This is false.

=========================
I emailed CCI (August 2016) and specifically asked them if the 550 small pistol magnum and 400 small rifle were the same primer. My email question:
"Are your small pistol magnum primers (550) exactly the same as your small rifle standard primers (400)?
There is a rumor on the internet that they are the same primer, just in a different box."
This was their reply:
"They are not the same primer, there are differences in the primer and you should follow published loading data. The web has some very dangerous information on it and anything that you use should be published and tested data."

I asked them what the difference between primers was, and they told me the mixture was different.
I've seen the exact opposite answer posted before by someone who also claimed to have contacted CCI so take it with a grain of salt.
Always good advice. Anytime a major component is changed, a reduction in charge and reevaluation of the load is recommended. Some major components are close enough in specifications not to require a full rework - cases come immediately to mind - but even then prudence dictates caution.work up a new load from the bottom of published loading data.
That's marks are due to the primers leaking etching the frame. Not whether magnum or standard but defective primers or loose primer pockets in your brass causing the gasses to leak out.If you choose to use them, monitor your gun for breech face erosion also known as pitting.
Cold weather function. The use case for CCI 450 are rifle cartridges that have a small primer pocket and need to ignite ball powder in cold weather conditions.1. What are CCI No450 Small Rifle Magnum designed for specifically.
