Hey guys. I have a open 2011 that are having light primer strikes. Tried Atlants arms ammo and reloads with every brand of primers. At 170 ish power factor, the primers that fire have a washed out look th them instead of a distict dimple. It is chambered in .38 super. Tried the same ammo through another sti open gun and the dimples look perfect. Any help please. Thanks, Tony
