This is the load Elmer Keith lists in his book "Sixgun Cartridges& Loads" (1936) . It is listed under/as : .38/44 Special and was to be loaded in Remington .38/44 Cases and fired in the S&W .38/44 HD Outdoorsman revolver .
He didn't say it ...but the 38/44 was not to be fired in lighter 38 special revolvers like the Colt Police Positive Special .
I would only fire this load in 357 magnum revolvers !
Interestingly ... Elmer's 357 Magnum load , same bullet w/ maximum charge of 15 grains 2400 ...
... but he reccomends loading 14.5 grs. 2400 !!!
Reading EK's Book on reloading is quite interesting ... you hear a lot about what he said but much is out of context or misquoted ... the book is reprinted at Amazon for about $10.00 and hearing the words straight from his pen is eye opening ... he knew a lot and I would tell anyone interested in reloading to spend the $10, everything he sys about bullet casting , lead/tin mixes , hollow/solid points and a few other things are still relevant ...
Nice read to boot ,
