discount north face a less than 0.5 lb

War, the focus of the people are focused on the search for a without increasing recoil case so muzzle velocity method can be improved. Way in Germany (which later will also detail description) using cone bore barrel, this barrel than the the parallel bore higher muzzle velocity of the projectile fired gun barrels. the British tried similar structure, but soon gave up. said the cone breechloader Another way, from the role of manufacturing kinds of composite projectile, the main components of this projectile with a diameter less than the bore diameter of the hard core of bombs, shells around the core surrounded by several soft shell made of lightweight metal, these soft shell diameter size coincides with the The barrel diameter suitable for shooting, metal soft shell near the muzzle off hard pits by much higher than the full-size projectile speed flew goals such shells is called a (abbreviation for the APDS), it is coming to an end of the Second World War by the British developed the first successful this projectile appeared greatly improve the performance of the service was easy to destroy anti-tank artillery, and until now still is one of the best means of attack on the tank.
Launch hard core projectile ultra most infantry weapons capabilities beyond all man-portable weapons capability, especially for light weapons, the best way, in fact, is the only - method is to use hollow charge. hollow charge through the work of a strange phenomenon, it works has yet to be fully appreciated. Initially, this phenomenon is known as the details of this phenomenon, the book is in the chapters will have to mention modern hollow charge projectile equipped with a cylindrical of zha drug blocks zha drugs block at one end of a tapered hole, the cone very similar to the role of the holes and the optical lens, it can be All the zha drug energy concentrated in one direction, generating a great Penetrating force of the fluid beam or jet, the energy and movement of the jet speed than the average plane blast wave is much larger. zha drugs tapered hole lined with a layer of soft metal such as copper this, then, the energy will also further enhance the natural, melting copper will also be jet away. in purely the zha drug energy effect, this jet can be armor plate melted, can be melted armor melt blown away, the results are quite amazing., a less than 0.5 lb (0.227kg) heavy small charge, if the design is reasonable and can detonate suitable distance, then, it can open a through-hole in a thickness of 9-10in (228.6-254mm) armored plate That is to say,discount north face, the use of a kinds of very small rockets is enough to be able to destroy a large tank. precisely because of the hollow charge,cheap nike nfl jerseys, before the emergence of Modern infantry anti-tank weapons became possible.
As a preface, wrote this point, for a number of complex technical issues described in subsequent chapters, we will take the simplest form possible, the aim is not to difficult to digest the technical details and terminology readers cause difficulties In any case, the principles in this book, is not the pursuit of details. fundamentally
