Good news, friends--I have a higher-velocity, lower-flash, more-accurate PD load, and I'm now carrying it.
After evaluating* 5 different charges of 4756 with the XTP124, 8.9 grains proved slightly better than others. This load develops 1407FPS from my 4.5" barrel (sample size 15; screens centered at 10'); the Gold Dot LE #54234 load produced 1354FPS from a sample size of 21 shots.
* with seven-each 5-shot groups over 2 days
