I have a brand new 10 inch 357 Max barrel for my Contender and I am going to run some LEE 200 gr, Flat noses for practice and some NOE 182 cup points for hunting. If I can reach 1700 fps with either bullet I will be happy. The Whelen will get a 2000 fps load using either the MP 220 grainer or the 200 gr. LEE. Might even experiment with velocities up to 2300 fps. Going to use H110 and 1680 in the Max. The Whelen will get tested with 2400, IMR4227, WC852 or any of several other powders I need to finish emptying their cans, R7, IMR4198,H322. It is deer season but the first 357 Max loading has already begun.
