Actually, the Federal 357s from the '70s and '80s was called (depending on it's vintage) both "Hi Power" and "Hi-Shok". Some Federal 357B came in red & white boxes. Later boxes were labeled "Hi Power", some weren't. The "Hi-Shok" came in silver boxes. None of the 357B loads were Hydrashock, just simple cup and core hollopoints loaded to 1400+ ft/sec from a 4" revolver. Talk about a loud report and bright flame if fired at dusk/night! Only Federal's 180 gr JHP 44 Maggie's were brighter!
