Used for double action revolver speed loading. Heavy bullet + slow speed = soft recoil. S&W 357 Mag revolvers have an 18 3/4" twist rate. This bullet may or may not stabilize at slow speeds. You'll have to experiment. 150 gr. might be a better option. But, 38 Super and 9mm revolvers have a faster twist rate, the heavy bullet works really well.
9mm revolvers will shoot better with .357"-.358" bullets
