Hello everyone. I was hoping some of you guys could chime in and help. I have a whole bunch of Winchester Super Target powder left. I want to reload the 357 magnum. After reading Jerry lesters information a few times, I've decided to use the Remington JSP's. I was hoping to use the 125 grainers so I could shoot them in my rifle and pistol, and as a bonus have my wife shoot them too. I cannot find anywhere on the net any information using this powder with the .357. Do any of you guys have a load worked up using this powder? Can I use this powder? Can I use it if I go to a heavier bullet? Any info you could pass on to me would sure be appreciated. I see it has been used alot loading the 38 special, so I would think I should be able to use it. Thanks, Don
