Here are the results of my recent testing:
15 grains of FFFg Triple 7 under a Speer 95 grain ball and 1/8" felt wad and Remington #10 caps.
The single-shot that appears at 5 O'clock was the very first shot fired through the gun. I fired it at 9 feet, rapidly drawn from the holster, and fired as soon as the barrel could be leveled, a sort of 'Old West Emergency Action Drill,' I guess you could say.
The next 12 rounds were fired at 50 feet from a traditional weaver-style combat stance, cocking the hammer with the thumb of the left support hand and firing at a fairly rapid pace.
The 3 headshots were fired at 21 feet, one at a time, from the holstered position, drawing the pistol quickly and firing as quickly as sight picture could be obtained.
