Yeah, that's the one source I've seen. I'm surprised there aren't more, considering how this was once such a popular caliber.
Well, such a widespread caliber.
It's a Victory, so it's plenty beefy for any loading I could put in the case. I'm just trying to feed it the WWII food it's craving….
In 1937 the .380/200 Mk I cartridge was replaced in British service by the .380 Mk IIz, which had a 178gr jacketed bullet.
The irony is of course that by the time S&W began manufacturing the British Service model in 1940, referencing it as .38/200, and Colt in 1941 even put that designation on their OP barrels, it had been overtaken by events.
According to Stamps/Skennerton, the standard reference on the Enfield for which the cartridge existed, it was the Tank Corps that first pointed out the susceptibility of the 200gr soft lead bullet to deformation and instability, causing possible Hague Convention issues.

It is still a bit of a mystery as to why the British contract for 18,250 Colt OP's were marked.38/200 when this Mark 1 had already been declared obsolescent before the war kicked off in September 1939 and the 178 grain Mk11 round was standard issue. I have never seen any documentation that casts any light on the matter.
