I recently obtained 3 lbs. of Winchester's old ball powder #571. I've found data for use in .40 S&W but would also like to load some heavier bullets (158-180 gr) in my .357 Mag revolver.
I've gone through some old Win. reloading guides and Lee's "modern reloading" but found no info. I even contacted Winchester but they were of no help at all, only to tell me to download their entire reloading guide which consists of a very few of their newest powders. Big deal! Guess they can't be bothered with their older powders.
If any of you reloaders out there know where I could find data for #571 in .357 or have a favorite recipe you wouldn't mind sharing I would be greatful. Thanks in advance, dgang
