Monsieur Black Jaque: Oui Monsieur, 200 grainers in a subnose. The Winchester factory load uses 3.8 grains of 231 under that bullet for a modest 770'/sec. But, being the modest guy that I am I certainly would not want to be standing in front of it when it goes off. Years ago the NYC PD reported that althought the 200 gn (roundnose) had adequate stopping power, it lacked the ability to penetrate (1950s) car bodies - go figger, those things were tanks - hence the NYPD policy of not trying to stop a speeding car with a 38. Col. Charles Askins used that 200 gr load in a British 38-200 Webley during WWII and based on his experiences carried either a 45 auto or a 38 spl with the 200 gn loads for his police work. On occassion he carried and used a 38 Super.
As for the 357, the 200 gn bullet over 12.4 gn of WW298 is supposed to get you 1330'/sec but the data does not show the barrel length. I have used that load from a 3.5" S&W to take whitetail out beyond 50 yds, with complete pass throughs. HTH. Mikey.
