IIRC, the FBI never actually issued the "full power" Norma 10mm loading as it was deemed to produce excessive recoil during the testing phase. Agents were issued the reduced-power Federal loading from the get-go which, depending on the source, delivered a 180-190gr bullet at 950-1050fps. Federal's current 10mm Hydra-Shok offering is about the closest to the "FBI load" in terms of ballistics that is still available, but the original used the older JHP design which I believe Federal now calls the "Hi-Shok".
