I am not sure I can get the name of the book right, it was written in the early to mid 90's about real world street shootings and they placed the .357 magnum at the top with one shot stops to the torso. Now days there are other calibers like the .357 sig and the .40 S&W has been around longer now and the book doesn't translate into total gospel but it is also hard to ignore the data of the .357 magnum and it's effectiveness with certain loadings. The .357 magnum may be obsolete with Law enforcement on a grand scale as a uniformed carry item but as a whole as a cartridge and it's usage all-around, I would say- No.
