Lesmoke power was virtually never used for centerfire cartridges, it wasn't really suitable.
It was primarily a .22 propellant.
Other semi-smokeless, or bulk black powder replacement, propellants were suitable for use in centerfire cartridges.
The last references I've been able to find to black powder loaded .38 Special are from about 1922.
