Rifle primers in 357.

[twoshooter]

I have never had any sm pistol mag primers, I am shooting the ammo in a rifle and have used sm rifle primers. I have not had any problems. Have any of you shot both, or do you know of either one being better than the other? I have sm rifle , but if the mag pistol would be a significant improvement I would look for some.

Per tech at CCI, the small magnum pistol primers and small rifle primers are the exact same primer. The small pistol primer has 3 micrograms less flash powder. I commonly use Federal match small rifle primers in my 357 mag loads. FWIW, the difference between match primers and normal is the operator on the machine. The one with the most experience makes match primers while the other operators make the same primers but are not labelled as match- they are in fact, the same primer. Only the operator is different on the machine.
