effing joke.

Briefly, the performance standards are simple. A handgun bullet must consistently penetrate a minimum of 12 inches of tissue in order to reliably penetrate vital organs within the human target regardless of the angle of impact or intervening obstacles such as arms, clothing, glass, etc. Penetration of 18 inches is even better. (give me an efffing BREAK). Given minimum penetration, the only means of increasing wound effectiveness is to make the hole bigger. This increases the amount of vital tissue damaged, increases the chance of damaging vital tissue with a marginally placed shot, and increases the potential for quicker blood loss. This is important because, with the single exception of damaging the central nervous system, the only way to force incapacitation upon an unwilling adversary is to cause enough blood loss to starve the brain of its oxygen and/or drop blood pressure to zero. This takes time, and the faster hemorrhage can occur the better.

The FBI Ammunition Test Protocol is a series of practically oriented tests to measure a bullet's ability to meet these performance standards. The result is an assessment of a bullet's ability to inflict effective wounds after defeating various intervening obstacles commonly present in law enforcement shootings. The overall results of a test are thus indicative of that specific cartridge's suitability for the wide range of conditions in which law enforcement officers engage in shootings.

The test media used by the FBI to simulate living tissue is 10% Ballistic Gelatin (Kind & Knox 250-A), mixed by weight (i.e., one pound of gelatin to 9 pounds of water). The gelatin is stored at 4 Centigrade (39.2 Fahrenheit) and shot within 20 minutes of being removed from the refrigerator. The temperature of the gelatin is critical, because penetration changes significantly with temperature. This specific gelatin mix was determined and calibrated by the U.S. Army Wound Ballistics Research Laboratory, Presidio of San Francisco, to produce the same penetration results as that obtained in actual living tissue. The 10 % gelatin has been correlated against the actual results of over 200 shooting incidents. Each gelatin block is calibrated before use to insure its composition is within defined parameters. Copies of the test protocol are available upon request for those interested in duplication the testing or reviewing the procedures in greater detail.

can't even DISCUSS handgun ammo that DOES offer temporary cavity permanent -damage, of course, (cause it's AP) This does require impact speeds of well over 2000 fps. The above is the actual wording of the fbi protocol, which so many "think" amounts to an effing thing. and no, they dont know more about it than I do.

So explain to me why we need all this highly specialized ammunition when after an apocalyptic event we only have to shoot zombies, and everyone knows that any old bullet will put down a zombie!!
