Not to get a old thread renewed , But , I will tell you that I have personally shot " the load " , 8.0 grs of HS-6 with a 158 gr bullet loaded in a 38 spl case . I fired these in a 357 ( 686) and they didn't seem really all that stout , compared to max 357 magnum loads . As a 38spl load , they were all you would ever want to shoot .
To shoot or not to shoot , it's up to you . But personally I would just shoot them , in a 357 . Regards, Paul
