"Did you know that in the infamous Thompson tests of early in the last century that most experts chose to totally ignore the fact that the .30 Luger did about as well as the .45 acp when shooting gigantic animal steers in the tests that took place in a Chicago slaughter house. The big bore boys that have been beating the big bore drums for years simply chose to ignore how well the much smaller but much higher velocity 30 luger did in killing the steers."
Oh?
Hum...
I danced with someone on this very subject some time ago (link at bottom of page...)
There's a very good summary of the Thompson LaGarde tests in the 4th Edition of Cartridges of the World. It coincides very nicely with my reading of a copy of the actual report when I worked for NRA.
In short, that premise that the .30 Luger cartridge did about as well as the .45 ACP can be summed up by a singled word...
FALSE
First, and most importantly, the .45 ACP wasn't tested. An earlier, prototype of the round, firing a 200-grain bullet, was tested, however.
"The second part of this Army test involved shooting into live animals in order to observe the actual effect on living tissue...
No shots were fired into vital organs such as the heart or brain, all shots being fired into the lung or intestinal areas.
With the .30 Luger, in no instances did an animal drop by the tenth shot and in fact none of them appeared to suffer great pain, shock, or distress.
Animals shot with the 9mm or the .38 Colt auto showed greater distress and by the sixth or seventh shot showed great distress, shock or exhaustion and usually dropped before the eighth shot.
With the .45 Colt revolver the animals showed great shock and distress and dropped by the fourth or fifth shot. With the .455 and .475 caliber revolvers the animal usually dropped by the third shot.
Those shot with the large calibers would begin to bleed from the nose and mouth by the second or third shot. This did not happen with the smaller calibers.
The major conclusions drawn from the Army lethality tests of 1904 were as follows:
1. Within the velocity range possible with handguns there is no marked effect from velocity alone other than greater penetration.
2. At handgun velocities there is little difference in the effect of different bullet materials (lead or jacketed) when traversing flesh. However, lead or expanding bullets will inflict more damage when they strike bone.
3. In fles there appears to be little difference betwene a sharpt pointed or round nosed bullet. On the other hand, a flat or blunt point does substantially more damage to blood vessels and bone and has less tendency to be deflected by bone or cartilage.
4. The weight of the bullet does not appear to be critical, although it is to be noted that the most effective bullets weren ot only of large caliber, but also the heaviest weight.
5. The diameter or caliber of the bullet
is important because at handgun velocities expansion of shot point or other expanding bullets is not reliable. The larger diameter bullets simply destroy more tissue and blood vessels becaus they affect a larger cross sectional area.
Quite frankly, the ONLY area in which rounds like the .30 were found to be more effective were in head shots, where their higher velocity increased the amount of destruction out of proportion to their size.
Here's a very interesting thread from The Firing Line on this very subject...
