I'll answer Coyotehunter's original question, "Don't use Accurate Arms #2 pwder in a 44 magnum case!" This answer is based on personal experience using AA data from Manual #1.

AA #2 burn rate is too fast for 44 mag cases. I could not find a "mid-range" load. Starting load was a soft pop until a certain point when the load became maximum bang. There was no happy middle, either mouse loads or war loads. Fortunately this experimmenting was done in a Ruger Redhawk before I owned my M629. The last 5 of the last 6 rounds fired, had to be forced out of the cylinder with a screwdriver.
