I just bought a snubby revolver (S&W 640 Pro). I have been a reloader for semi-autos and carbines for many years. However, a short barrel revolver is a different animal. I am looking for loads for practice and defense using 110 gr. & 125 gr. JHP bullets. I'd like to minimize muzzle flash. Conventional wisdom would indicate using a fast burning powder. The fastest I currently have is Hodgdon Titegroup (#15 on the 2018 Burn Rate list of 150 powders). The next would be Alliant Power Pistol at #34 on the list. Suggestions?
