I have been using my .357 for white tail for whats going to be my 3rd season this year. A friend of mine has always made up about 200 rounds of nearly max load 158 gr hornady xtps with HS6 powder. Now that i have begun reloading for myself i see there are powders that are capable of more speed at lower pressures, which to me translates into more energy, flatter trajectory, and less wear and tear on my gun. My lee load manual states that with H110 at 16.7 gr, i could push a hornady xtp 1591 fps, while i wouldnt go to max load, that figures up to roughly 890ft lbs at the muzzle. My question to you, are these velocities acheivable in a revolver with a 6 inch barrel or is this geard more towards the .357mag rifles? Your help is appreciated.
