A gun, one of Mans most controversial, but yet useful tools. It is used to hunt, to protect, for fun, and, unfortunately, to take lives. We are scared about them, but we would not really be here without them. This nation was won with the aid of these tools. And even more importantly we wouldn’t be here without ballistics-the bullet and its cartridge, and the barrel. In scientific terms, it is called Interior and Exterior ballistics. This paper will cover only the beginning of ballistics and firearms, because it is such a vast expanse of information and it varies with each firearm. Why I am interested in ballistics and firearms is that I want to know more about them altogether, more importantly I want to know about the projectiles, the powders used to fire them, and the barrels of firearms. In the past 200-some odd years, the world of guns and powders has changed completely. we went from muskets and black powder with lead shot to high powered, high caliber rifle rounds able to travel many miles and go through very large walls, something we could have never imagined to do 200 years ago. What I already know about ballistics and firearms is that the grooves in the barrel are unique to each gun, that there are many different types of bullets, calibers, powders, and primers. And I know almost a drop of what the full expanse of what my research is going to have to cover. There is a lot to learn.
What I want to know about ballistics and firearms in general is that how did we get the equations for external ballistics? How did the barrel of firearms change to what it is now? Why is there more fouling (dirt and gunpowder residue) of barrels that used black powder than in barrels that used smokeless powder? Why is gunsmithing almost disappearing as a trade? Why do people feel so tense and defensive about firearms? And how does forensics figure out the type of firearm a bullet has been fired from?
