Sheep Collisions: the Good, the Bad, and the TBI
Michael Courtney, Amy Courtney
The title page of Chapter 9 in Fundamentals of Physics (Halliday, Resnick, and Walker, 8th Edition, p. 201) shows a dramatic photograph of two Big Horn sheep butting heads and prom…
An Acoustic Method for Determining Ballistic Coefficients
Michael Courtney, Amy Courtney
This paper presents a method for using a PC soundcard, microphone and a chronograph to determine bullet BC with an accuracy of 6%. This is useful when a second chronograph is unava…
The Truth About Ballistic Coefficients
Michael Courtney, Amy Courtney
The ballistic coefficient of a bullet describes how it slows in flight due to air resistance. This article presents experimental determinations of ballistic coefficients showing th…
A method for testing handgun bullets in deer
Michael Courtney, Amy Courtney
Using service handguns to test bullets in deer is problematic because of velocity loss with range and accuracy giving sub-optimal shot placement. An alternate method is presented u…
Review of criticisms of ballistic pressure wave experiments, the Strasbourg goat tests, and the Marshall and Sanow data
Michael Courtney, Amy Courtney
This article reviews published criticisms of several ballistic pressure wave experiments authored by Suneson et al., the Marshall and Sanow "one shot stop" data set, and the Strasb…
Ballistic pressure wave contributions to rapid incapacitation in the Strasbourg goat tests
Michael Courtney, Amy Courtney
This article presents empirical models for the relationship between peak ballistic pressure wave magnitude and incapacitation times in the Strasbourg goat test data. Using a model…
Relative incapacitation contributions of pressure wave and wound channel in the Marshall and Sanow data set
Michael Courtney, Amy Courtney
The Marshall and Sanow data set is the largest and most comprehensive data set available quantifying handgun bullet effectiveness in humans. This article presents an empirical mode…
