Handgun cartridges get handgun primers, even in a rifle.. Problem is getting them mixed up with ones used in handguns which may or may not work.

You are fine running small rifle primers in 357 brass in whatever platform you want to. The only issue might be if the primer cup on the small rifle primer is thicker or tougher than the pistol primers, and your firing pin spring is too weak. I don't think it is going to be an issue though, because CCI, for example, uses the exact same primers in their boxes labeled "CCI 400 Small Rifle Primer" and their boxes labeled "CCI 550 Small Pistol Magnum Primer". The exact same primers.

HEY ALL...thanks for all your help...I have enough small pistol regular and magnum to last for probably the rest of 2021...i found a brick of Federal #205 small rifle in my stash and was just wondering if they would be ok to use in 357...what with this drought of ammo and components...
Thanks to all again...

If that is true, can one use CCI Small Pistol Magnum primers in .223 AR loads, I have loaded about 1000 .223 with CCI Small Rifle with no problems, but I am out of them now. I do have about 3000 of the CCI Small Magnum Pistol though

pistol primers are softer than rifle primers and to the most part have less energy.

Remington 6 1/2 primers are some of the softest and lowest energy small rifle primers, I believe.

If you use rifle primers in a pistol cartridge there are a couple of things to keep in mind.
You probably should lower your maximum load as pressure will likely be higher.
t seems to me that I loaded some pistol ammo with rifle primers, many years ago and the rifle primers were dimensionally deeper than pistol primers - but that is a hazy memory. Quite frankly I do not remember if it was small rifle primers in a 357 or large rifle primers in a 44 Magnum. But I think it was likely the 357 as that was my first pistol - a Herters Model perfect that I mail ordered and got it shipped to the door, no FFL was needed.

If they will fit firmly in the primer pocket, you can use them. No, that's not what any of the loading manuals will say, but I've never heard of anyone hurting themselves or their firearm using the "wrong" primer.

SS, i have used small pistol mag primers in my 223 and 300 bo rounds for practice. One of my most accurate 223 loads out of a sav 10 was with pistol primers. Had a 72% one shot kill ratio on ground squirrels at 425 yards. Sold that rifle like the idiot i am!

There was a video on youtube I will see if I can find it.
I would still be cautious and load up but the result was that there was basically no difference.

From what I remember reading years back the heat and amount of flame produced differed between primer types and primer makers, which was related to the amount of powder each type was supposed to ignite. But I don't think more flame in less powder is going to make a difference.

FOUND IT
