I pack a 2in S&W model 19 for daily chores around the ranch place. Within it's chambers generally resides a 158gr "Keith Style" (if there is such a thing for .38/.357) SWC over 15gr of 2400. I set them in .38 spec cases and clearly label the as .357 so as to avoid mistakes. I read about this load years ago as a pet load of Mr. Skelton, and being a less than experimental fellow, have used it ever since.
