I am not sure why Hodgdon uses a 10" barrel for their .357 load data, however as an interesting point ,I found a video of a reloader trying to duplicate the Buffalo Bore 180 gr. ,357 load, advertised at 1400fps, he used the Hodgdon data, with Lil' Gun powder and was getting around 1400fps with his 4" GP 100.
