Simple Technical Question: Ballistic Gel Penetration

[94045]

The calibration b is fired at 590 +/- 30 FPS. That's quite a bit higher than the velocity from a spring gun.

From where comes the assertion that is would bounce off human flesh?

You know you have a point. Just because an 880 is rated at 750 fps doesn't mean it is actually doing 590 fps at 20'.

Chrono time...

There you go! Actual testing is always the answer.

Ballistic gel isn't intended to accurately predict how far bullets will actually penetrate in living humans or animals. There are too many variables. There is no guarantee that a bullet which penetrates 18" in gel will penetrate 18" in a human. But a bullet that penetrates 18" in gel will penetrate deeper in a human than a bullet that only penetrated 12" in gel.

This.

Ballistic Gel isn't a perfect simulation of human tissue, it's an approximation. You can use it to predict penetration of one type of round or load VS another, as a standard of comparison.

The other important variable here could be how far the trajectory at impact differed from the surface normal.

I simply want to know why the bb will bounce off humans at the same velocity it will penetrate 3.5" into properly prepared gel.
