i recently picked up a gp100 in .327 fed mag. i am looking to reload for it. my newest book [speer #14] doesnt show anything for this gun. i am looking to load hornady 100grn xtp over win 296 powder. i cant find what primer is being used. any help would be apprecieted.
i found several different sites that show a maximum 13.2 grns of 296 for muzzle velocity of 1525 but none list the primer
