Anyone have a link documenting any hardness difference between Federal Magnum Small Pistol primers and Federal Standard Small Pistol Primers?
Thanks

Cup thickness/hardness is the same between standard and magnum of the same brand. The compound for ignition is different.
In those few pistol cartridges that operate at rifle pressures, rifle primers are typically called for which is where the cup thickness/hardness comes into play.
