stopping power

The effectiveness, or stopping power, is of prime importance.

The stopping power of a substance is proportional to the square root of its atomic weight.

The stopping power of an atom is not altered if it is in chemical union with another atom.

A pocket pistol of all pistols must have instant stopping power, as the shooting is done at a few feet or even inches off.

England, having to fight savage tribes, had always preferred a large bore pistol with stopping power.
