Overpenetration

Nothing sexual here, just a footnote to the reference in this post yesterday on the tendency of some bullets to “overpenetrate” and kill someone else.

From This is True:

What happened in a street robbery was perplexing police in San Francisco, Calif. Two teens robbed a man, who cooperated with them. One of the teens pulled a gun and shot the man anyway — in the face.

But the victim didn’t fall dead, the other teen did.

Police at first wondered if there was a rival gang member who shot the robber. But after investigation, they found that the teen’s bullet glanced off the victim’s face, and hit the accomplice, Clifton Chatman, 16, killing him instead.

Police are seeking the suspected shooter, who is also 16. (RC/San Francisco Chronicle)

Many times this problem has been mentioned with regard to the 9mm x 19mm luger round. The debate’s been going on a long time.

This was a good explanation:

Any round that does not expend it’s energy inside the intended target will over penetrate. A .22 solid will go clear through a human body if it doesn’t strike a large bone.

Chose your hollowpoint ammo properly and the chance of over-penetration is minimized but never impossible.

The only place a “hardball” round should be loaded is at the target range.
