Has anyone tested or received the loading data for .45 ACP cartridge cases designed to be primed with SPP's coming from Federal instead of large? Would I need to add a few more grains of powder to achieve the same mussel velocity as a cartridge primed with a large primer? Right now I'm using 230 gn round nose, copper plated bullets, and a powder charge of 5.8 gn or Winchester 231? Will the small primers require more, less or the same powder charge?
