The original load for the .38 Special has been given as 21.5 gr of black and a 158 grain lead roundnose . . .
Jim, I do not believe that the 38 Special was ever commercially loaded in black powder. If anyone has ever found a box of BP 38 Special please post.
It is not correct. The .38 Special cartridge was a smokeless round from the very beginning.
Note that the post linked to in TripleLock's post perpetuates the myth that the .38 S&W Special was introduced in 1902! "Cartridges of the World"** also repeats this as well as at least one major re-loading manual, Speer** as I recall. Where this ever started I have no idea. Maybe that is the year Colt adopted the cartridge (as the .38 Colt Special)? Unfortunately Suydam makes no mention whatsoever about the Colt variant.
** Just shows re-loading manuals aren't the place to look for reliable/accurate historical information on cartridges!
Thanks for all the very interesting information. I want to shoot black powder because of the era into which this revolver fits. I have been a black powder shooter for over 40 years, mostly flintlocks. I have been shooting black powder cartridges I have loaded in my buffalo rifle (.45-70), so I am familiar with how it is done. Besides, BP is just so much more fun!
My only question about the text of the book Alk8944 referenced is why would the government send 38 Special ammunition to S&W if that was the company that invented the caliber??
