Book Description
For the law enforcement officer and the civilian who may be in a situation that requires the use of a handgun to stop a lethal threat action, it is important that the person differentiates between the crass, glib and self-serving advertisements of ammunition vendors and the reality of how, what and why effective stopping power occurs. Factors to consider are the physiological response, the psychological response, the time frame parameter and bullet efficacy. Of these four factors, only bullet efficacy can be somewhat controlled by the person, this only by understanding how and to what extent the bullet contributes to the degree of stopping power obtained. A number of concepts / formulae have been included so as to permit the reader to consider their merits and whether or not they are consistent with the reality of biology, physics and other relevant sciences. Finally the material in this book is intended to permit those persons to instruct, teach or make decisions regarding the selection of a service handgun/cartridge combination that will help to provide the means to prevail in a lethal threat confrontation. About the Author: Mr. Bredsten retired from the Federal Law Enforcement Training Center/Firearms Division (FLETC/FAD). With FLETC/FAD he performed duties as a firearms instructor and he also taught ballistics to the FLETC/FAD staff and to students in the Law Enforcement Rifle Training Program and in the Precision Rifle (Sniper) and Observer Program. Subjects covered included the ballistic coefficient, barrel time, the coefficient of reduction (form), Greenhill formula (rate of rifling twist), firearm recoil, bullet time-of-flight, bullet drop, bullet midrange, wind deflection, bullet penetration potential and bullet terminal (wounding) efficacy. Since retiring he has provided ballistics consultation service for the FLETC/FAD, the Transportation Security Agency, the Orange County (Florida) Sheriff's Department and Exxon Mobil Corporation. Mr. Bredsten attended and completed various classes/courses relating to firearms (e.g., H&K MP5, Steyr Aug, Uzi, Tactical Speed Shooting and advanced shotgun) and ballistics (e.g., the first and second International Wound Ballistics Conferences, a Federal Law Enforcement Ammunition and Ballistics Seminar and Oehler's Ballistic Instrumentation). Mr. Bredsten has an AA degree from Chaffey Jr. College and a BA degree from Sacramento State College and currently resides in Georgia.

Book Description
The science of small arms ballistics is seriously underdeveloped and underappreciated. This unique and different book is a comprehensive study that fills a legitimate need for a work that covers the engineering and theory of small arms ballistics. The author shares his extensive research on working out the science of small arm ballistics mathematically and explains his theories, such as the field-effect and the field-effect over trajectory and time, along with new theories on interior, exterior, and terminal ballistics. Each equation describes a mathematical relationship, such as transfer of energy, and has an engineering application to help solve a design problem. Some equations, such as the calculation of bullet length with a given muzzle velocity and rate of twist, represent manipulations of those equations. Some other equations represent a set of mathematical instructions to resolve a technical problem, such as the computation of trajectory or depth of penetration of living tissue in real-time.

Book Description
In Quantitative Ammunition Selection, Charles Schwartz presents an accessible mathematical model that allows armed professionals and lawfully-armed citizens to evaluate the terminal ballistic performance of self-defense ammunition using water as a valid ballistic test medium. Based upon a modified fluid dynamics equation that correlates highly (r=+0.94) to more than 800 points of manufacturer- and laboratory-test data, the quantitative model allows the armed professional to generate ballistic test results equivalent to those obtained in calibrated 10 percent ordnance gelatin. Using data generated from water tests, the quantitative model accurately predicts the permanent wound cavity volume and mass, terminal penetration depth (+/- 1cm), and exit velocity of handgun projectiles as these phenomena would occur in calibrated 10 percent ordnance gelatin and soft tissue. A retired law enforcement professional, Schwartz provides a concise explanation of the relevant principles of mechanics, fluid dynamics, and thermodynamics pertaining to the model and its derivation. The quantitative model is clearly presented with illustrated computational examples that provide guidance to the armed professional in every aspect of the model's application.

Book Description
This fascinating book starts with the basics, going back to the days of muzzle loading before considering the various attempts made over the centuries to improve the bullet. It moves on to examine the development of the cartridge right up to the present day, and provides the reader with a clear understanding of the principles governing the bullet's flight. Topics covered include the factors that influence ballistic performance and accuracy; 'internal ballistics' (factors influencing performance whilst the bullet is still in the barrel) and 'external ballistics' (factors affecting the bullet's flight when it leaves the barrel). Simple formulae are included to enhance the understanding of the principles involved. The book also describes a number of interesting experiments concerning performance and accuracy and presents the results. It aims to assist those enthusiasts who make their own bullets by analysing faults that have an impact on accuracy and covers both rifled firearms and smooth-bore guns.Includes a glossary that incorporates rifle terminology and those terms specific to the shotgun, and is superbly illustrated with over 100 colour photographs.

Book Description
Shooting Incident Reconstruction, Third Edition, offers a thorough explanation of matters from simple to complex to help the reader understand the factors surrounding ballistics, trajectory, and shooting scenes. Forensic scientists, law enforcement, and crime scene investigators are often tasked with reconstruction of events based on crime scene evidence, along with the subsequent analysis of that evidence. The use and misuse of firearms to perpetrate crimes from theft to murder necessitates numerous invitations to reconstruct shooting incidents. The discharge of firearms and the behavior of projectiles create many forms of physical evidence that, through proper testing and interpretation by a skilled forensic scientist, can establish what did and what did not occur. Written by the world's most well-respected shooting scene and ballistics experts, the book addresses the terminology, science, and factors involved in reconstructing shooting incident events to solve forensic cases. It covers the full range of related topics including: the range from which a firearm was discharged; the sequence of shots in a multiple discharge shooting incident; the position of a firearm at the moment of discharge; and the position of a victim at the moment of impact. The probable flight path of a projectile and the manner in which a firearm was discharged are also discussed. Case studies illustrate real-world application of technical concepts, supported by over 200 full-color diagrams and photographs. This book will be of value to practicing forensic scientists (firearm and toolmark examiners), ballistics experts, crime scene personnel, police departments, forensic consultants (generalists), attorneys and judges, medical examiners (coroners), and forensic pathologists. - New chapters on special reconstructive properties and value of shootings involving sub-machine guns or pseudo automatic firearms, rate of fire with special attention on shot-to-shot time intervals, human factors in shooting incidents - Updated and revised glossary terms to fit with new technology and the emergence of standardization of terms by groups such as the Organization of Scientific Advisory Committees - Provides clear practice standards and ethical guidelines for those involved in reconstructing shooting scenes
