Now that I am retired and reloading for SD practice, I try to shoot ammo that replicates the duty ammo (180 gr Gold Dot JHP) issued by the Sheriff's dept. as well as my son's police department. Using WSF or WST, I start with a medium load and work tenth of a grain increments towards the maximum loads, checking feeding, ejection, accuracy and recoil of each load at distances of 5, 10, 15, 20 and 25 yards with a standard police silhouette target. When I can consistently put rounds accurately in center body mass with controllable recoil, that feels like I am using duty ammo, that becomes my standard load.
