Give me what you think will be some of the top powder choices with a 357 Magnum with a 10" - 13" barrel using 170 and 180 grain bullets?
Harry1969 beat me to it. I have had great luck with 300MP in .357. The only place where I have had issues with it is on minimum loads in cold weather. It seems to have some ignition issues under those circumstances.Nothing beats Power Pro 300 MP for max loads. Check out pages 4 and 5 of this PDF from handloader magazine. Some of those 357 magnum loads have over 850 pounds of muzzle energy from a 6" barreled GP100. The 44 magnum loads with heavy bullets are also impressive.

Do you think 1500 ft./s is realistic with the 170 grain Sierra in a 12.5-13" barrel with H-110?
I'm not sure because I never tried it and I'm not good at guessing how much velocity is lost with shorter barrels.Do you think 1500 ft./s is realistic with the 170 grain Sierra in a 12.5-13" barrel with H-110?
