I have CCI small pistol magnum primers that I want to use for reloading my 9X19 and .40 S&W. Reloading data for these calibers is sparse for magnum primers, but I want to use them anyway because I have so many. Does anyone know where I can find reliable data for mag. primers and True Blue powder, or does anyone have a conversion factor that will compensate for the difference between standard and mag. primers? Thanks.
