For pistol, typically 3 meters; also some shots at 25 meters.
For rifle, typically 3-10 meters, 100 meters, and 300 meters.

As the Doc has stated, live tissue is not homogenous. It is composed of a variety of very different tissues of varying densities and strengths. Properly calibrated ballistic gelatin is only a calculated approximation of the live tissue found in our body. It can only ever be an approximation because it is, by it's very nature, a gross over simplification of the human machine.
Further, bal-gel does not account for the striking of bone or bones, nor does it account for the elastic strength of the skin on the back side of the body. In a torso shot, the skin on the exit side can be equivalent to nearly 2" of calibrated bal-gel penetration.
Either way, we arrive at the same conclusion....over penetration is much less of a concern than under penetration.
It takes about 125 fps just to penetrate skin and 200 fps to penetrate bone. Then, if the subject is wearing clothing, who knows how much velocity is lost due to that? Especially if it is nylon, a material used for the original fabric body armor.
Gel is just a laboratory substance that enables us to compare apples to apples.

INNOVATION IS SELDOM ACCOMPLISHED WITHOUT CONTROVERSY.
My first rule of a gunfight, thanks to John Farnam's wise advice. "Get away from there!"
From the various shootings I've responded to over the years (the last one being about 10:30 PM last night - bullet entered the upper left back area, traversed down and to the right, missing anything important) I've seen bullets over and under penetrate and stop the individual. I've seen bullets over and under penetrate and fail to stop the individual.
The above quote best sums up my current thoughts on the subject.
A reliable gun, good tactics appropriately used, and shot placement. Repeat if necessary until the incident is over.

I prefer loads in the 13.5 to 15 inch penetration range... and I like them to be as uniform as possible in various barrier testing (barrier blind).
