Food for thought to all you who carry small caliber side arms or have women who carry small caliber handguns.

Very interesting stuff! Thanks for posting...

I agree, very interesting. I've only glanced through it so far, but it sounds like the information would support the use of a high velocity pistol round like that fired by the FN Five-seveN (5.7mm bottle-necked cartridge), if it was a PSP variant. That tends to go against the "common wisdom."

The only problem with this study and this type of study is that it deals with after the facts. Yeah, the doctors cut up the bodies and see the wounds, but it doesn't take into the psychological aspect of the wounded.

We know that a bullet in the bullet will kill...eventually. What we can't predict is if the wounded will drop dead right then and there or keep on fighting for the next several minutes.

The hydrostatic shock of a .44 magnum is enough to keep someone down. Compared to a .40 S&W, the .44 magnum has around 3 times the energy, about 1,500ft-lbs. Size matters.

.44 Magnums don't go fast enough to generate hydrostatic shock.

And the hottest .44 Mag load runs around 1200-lbft, which is pretty considerable, but it ain't no magic bullet either.

a 300gr JHP will produce 1500-ftlb. Where does hydrostatic shock begin?

2000+ FPS?

Dear folks:

It is not just the potential energy (MxV) that causes incapacitiation. It is energy TRANSFERRED / Time. The greater amount of energy transferred to the target over the shortest possible time in the proper target area is what causes the most damage and shock.

If you read the whole article, the whole point is to identify calibers and ammo that CAUSES THE TARGET TO STOP FIGHTING. Please also note that this study is 20 years old. There have been numerous advances in ammo tech that have completely changed the landscape of ammunition effectiveness. (Frangibles, "sawtooth" ammos, ect.)

Some of the new ammos in 32 are more effective than .45 ball.

Hydrostatic shock probably begins at around 2200FPS at the point of impact.

Last line - "Of those that will penetrate, the edge is always with the bigger bullet." See, 9mm sucks.
