Which term is defined as measuring the overall length of the shot pattern from the center of two bullet holes?

The term that is defined as measuring the overall length of the shot pattern from the center of two bullet holes is known as Extreme Spread. This measurement specifically focuses on the distance between the farthest apart bullet holes within a shot group, which can provide insight into the consistency and accuracy of a shooting performance. Extreme Spread is particularly important in assessing how well a shooter can maintain a tight grouping, especially when precision is critical, such as in competitive shooting or when engaging targets at varying distances.

Understanding this concept helps shooters evaluate their performance and the effectiveness of their shooting setup, including the firearm, ammunition, and optics being used. Analyzing the Extreme Spread can also be instrumental in making adjustments for future shots to reduce variability and improve accuracy.
