I’ve just started reloading .223 Remington for my AR15, and I had someone tell me that there are primers that I should specifically use for .223 in an AR. I checked my load manuals, and they all call for Small Rifle Primers. He said if I wasn’t sure, then to use Small Rifle Magnum Primers because SRP would cause slamfires.
Why would my manuals call for small rifle primers if Magnum primers were needed? Is this an urban legend, or something I should be concerned about? The primers I’m using are Winchester and Wolf.
