Well, yes. Did you read the entire thread? My post (perhaps I wasn't clear enough) was about an attempt to replicate the 38/200 with my 38 Special. The only difference between the two cartridges is that the 38 S&W (aka .380 Mk II, 38 Colt New Police, 38 S&W Super Police, 9x20mmR) has shorter brass (.775" vs 1.155") and has slightly larger bullet diameter (.361" vs .357"). It's relatively easy to download the 38 Special to 38 S&W velocities.

I suppose you could boost the velocity of the 200 gr. bullet in both cartridges if you wished, as long as you fired both in strong-enough revolvers....and not the ubiquitous break-action revolvers that S&W produced mostly in the 19th century. But my experiment was an attempt to replicate the 38-200 load used in the 38 S&W Victory M&P.
