Good article.  Thanks for posting that.

The article agrees with much of the FBI protocols.

This was interesting:

“In an eight-inch barrel, 30-grains of 3Fg Goex black powder, under a 140-grain round ball will have a velocity of 882 feet per second, and an energy level of 242 foot/pounds, which is well above our 200 ft/lbs power floor. Reducing the barrel length to five and a half inches reduces velocity to 805 fps, with a power output of 201 ft/lbs, so it still makes the grade. But, when the barrel is cut to three-inches, velocity drops to 550 fps. That gives a power output of 94 ft/lbs, which is in the 25 ACP range. It is not going to be a reliable fight stopper.”

The article says round ball is the best one shot fight stopper but seems to overlook the advantages of a wide meplat heavy slug.

Goex is not very energetic.  Those numbers would go up using various other powders.
