The reason for the use of magnum primers is the floating firing pin in the AR-15. If you ever extract a live cartridge out of an AR-15 chamber you’ll see a slight primer hit. The magnum primers and many match primers have thicker primer cups which resist slam fires. CCI 450, CCI 41, BR4, Remington Magnum small rifle primers and Federal AR primers have thicker cups.
