I am currently loading a 38 spl case, 148 gr HBWC with 2.6 gr of WST for light loads in PPC shooting. I am happy with that load but would like to change to a 357 case. I am shooting a 357 revolver and would like to change the case to 357 to fill the chamber and make cleaning easier. What changes in performance would you expect if this same powder charge was used in the larger volume case? Any recommendations on how to adjust the powder to abtain the same performance characteristics as the 38 spl case?
