This is a demonstration of the Effective Firearms’ Guide to Stopping Power Indices phone app, which provides up to 6 indicators of bullet performance.
The app provides the momentum, muzzle/kinetic energy, Taylor Knockout Factor, Thorniley Stopping Power, Hatcher Relative Stopping Power, and the expanded Hatcher value when relevant.
This example compares a contemporary .380 load to the classical 38 Special load.
The purpose of this video is simply to demonstrate usage of the app. No claim is made regarding the fitness or appropriateness of the values produced. Please do not email with complaints/opinions on the validity of the numbers.
