I've not used small rifle primers in a CZ 75B. I have used them in my P07 .40 S&W. Lights them off just like small pistol primers.
I've read, on other forums, that some people buy small rifle primers and use them for their .223's (AR15) and 9MM pistols.
Did the "AR15" give the forum away?
I never think about that when I'm buying primers, I end up coming out of the gun show with small pistol and/or small rifle primers, every time.
