A One-Shot-Stop Hit is a topic highly written about and highly discussed in
gun magazines.
Sanow, Marshall, and Fuller are usually associated with the statistical
discussion of this topic and Sanow and Marshall have written two books on the
topic (the second book with Fuller).
One-Shot-Stop Hit is usually described as a "solid" torso hit. Refer to
magazines and books for more description.
It must be noted that a missed One-Shot-Stop Hit is not necessarily a miss
of the target.
