Well if this helps, I can give ya loads from the Sierra manual for 60 gr, 63 gr, 65 gr, but no 62. You're gonna have to give us a little more info like what kinda of powder do you plan to work with cause the manual lists 18 - 19 different powders.The velocities for all those loads range from 3000 - 3600 fps and the 65 gr bullet requires a 1 x 10" barrel twist.
