9mm vs .45ACP

You are mistaken. The.38 super was not developed until the late 1920s. Earlier Browning guns, not the 1911, were chambered in.38 ACP, a less powerful cartridge. The final version of the 45 was developed per Army directive and was different from what Browning originally proposed.
 
I see all these ballistic gellatin tests, and wonder who has 12+ inches of flesh in a straight line? We've got these wonderful things called bones that can mess up any scientific penetration test. I'm more concerned with which bullet transfers more energy to bone and which one is more likely to bounce around inside the bad guy pinball style? If you are shot in the chest, which round is more likely to deflect off a rib and go in the wrong direction? Which round has the best damage AFTER punching through the sternum?

Has anyone gotten a multitude of pig carcasses and shot them in the same spot and compared the damage? I'd believe that to be a more realistic test than some guy shooting a block of glorified jello in his back yard. If someone could point me towards ballistics gel tests with bones included, I would be rather grateful.
 
You misunderstand gelatin. It replicates the average mean density of all tissue in thebody. That is why it correlates so well with actual shootings.

AS for body penetration, not every shooting takes place with the target facing you squarely. Punch through an arm on an angle and you can be shouting through much more than 12 inches of flesh.

Going through an arm is one of the main reasons why the one shooter in the miami fight was able to keep going for so long. His arm asorbed much of the energy and it stopped just short of his heart. The wound was fatal but not as quickly as it would have been using the new bullets that penetrate far better.

Make no mistake about gelatin. It is by far the best medium ever developed and it compares to actual shootings far better than anything else even pigs
 
Last thing on gelatin. You start putting bones in it and its corollelation to actual shootings goes way way down to the pint whee you may as well be shooting at brick walls.

The FBI standards discuss development of the criteria.
 
My mistake Mike. I had just figured going through multiple changing densities would make a definite difference compared to a single density. Don't really understand the concept but I'll take your word for it.
