Everything changes with time including Smith and Wesson revolvers...Just a short quote from Buffalo Bore and there heavy cast loading for the .357 Mag.
. You'll notice that new S&W revolvers with short barrels are often shooting faster than older S&W revolvers with longer barrels. The new S&W revolvers are very good and are made with equipment that makes them more consistent and faster than the S&W revolvers of yesteryear.
