It would be necessary to research old data from a variety of sources for the best answer, but I suspect Winchester 540 shotgun powder gained popularity as a handgun cartridge powder under the Hodgdon HS-6 designation. Winchester data promoting 540 for handgun cartridges probably came later. Possibly the experts here would know if this is a correct summation.
