I have absolutely no expertise in analyzing the relative "ability" of various calibers, let alone various bullet designs within a caliber.This ballistics stuff is interesting but I have a question.
Does anyone know how the density of gelatin compares to a human body?
I've seen some tests done on animals that I think are more realistic, after all if you have any real interest in penetration, expansion etc it's not because you intend to shot a block of jello in self defense, is it? I may be wrong.
But, I do have a mechanical engineering degree. And I spent 31 years analyzing "complex systems", both in tests and in field performance data. OK, it was automotive safety stuff.
So, I'll just say my belief is that "ballistic gelatine" is just a method of trying to eliminate a vast variety of factors that affect how a given caliber/bullet design will perform in real life.
This is "necessary" for comparison. There is just no way that real life factors can be properly analyzed to separate their individual contributions to "real life stopping power".
Even the concept of utilizing live primates (say apes or chimps) to properly separate "factors" can't be done. It would require thousands of animal deaths.
Even one death would not be politically correct. Or, in my personal opinion, it would not be ethical. If you don't know, more than a hundred years ago tests were performed on
human cadavers suspended by the neck, and also on live steers. "A series of up to 10 shots were fired into the lung or intestinal area of the animal after which it was humanely dispatched."
"In 1991 a privately funded group was formed to study the physiological effects of bullet impact on medium-sized animals. These are now known as the Strasbourg tests. These tests were
politically very sensitive in nature as the animals were shot whilst in a conscious condition."
Here is one of the very best (and relatively short) discussions of these tests, gelatine, Major Hatcher's development of his "Relative Stopping Power" calculation, Evan Marshall's 15 year
collection of actual shooting data and his analysis of "one-shot stops".
