Taschenbuch. Zustand: Neu. Neuware - 296, 6×9 pages: A deep dive into how the modern self-contained cartridge works. The focus of the chapters in this book is to explain what happens inside a typical sporting arms cartridge case after the primer ignites and how case design influences how the primer blast interacts with the propellant and case and how the propellant ignites, burns, and interacts with the bullet, case, and bore. These discussions reflect analysis of laboratory and other experimental data from Rheinmetall, Norma, and the Author proving how and why case design matters to accuracy, ballistic efficiency, barrel heating, and bore life. Among these discussions is a plethora of information proving most folk's intuitive understanding of how cartridges work is woefully lacking, at best. The Internet Forums are rife with drivel offered by self-aggrandizing, self-appointed experts who make statements such as: Neck length does not matter., proving only one thing: they know less than nothing about the subject.The goal of this book is to set the record straight with information behind the development of the ideal bottlenecked case design and the work that led to the parametric patents supporting the claim that bottlenecked case design does matter and that an ideal bottlenecked case design does exist. In some ways, the advantages of the ideal design compared to anything else are modest, in other ways, the differences are significant.…
