I worked up to that top load. That one wasn’t terribly consistent, giving velocities between 1674 and 1836 from a 5.5” Blackhawk. Some of the lower charges gave more consistent performance. In spite of this, the top end load gave the best accuracy, with an 8-shot group of 1.7” at 25 yards. I never really noticed the blast, although everyone talks about it. I shoot outdoors with hearing protection. Seemed similar to .357 Mag to me.
