Load Data is drawn from ballistic laboratory testing, GSCs own testing, a database of all manufacturers and two programs to crosscheck the data.
Load Data also includes powders from all regions in the world.
GSC has a QuickLoad file that is more comprehensive than the GS Custom file that comes with QL. Delete the gscustom.bul file that is in QL and replace it with the file that we supply. In QuickLoad, make sure that the Friction Proofing box is unchecked and, whatever the Weighting Factor is, reduce it by 0.10, when working with GSC drive band bullets.
