Bullet

History The first bullet proof armor was invented in 1897 by Korea and the Japan, it was made of 30 layers of silk, which in that day could stop a black powder bullet it was nicknamed “soft armor.” But then when firearms became more powerful it became useless. So a priest from Chicago made it better by weaving 1.6mm steel plate between four layers of silk, he proved it was “bullet proof” by having a man shoot at his chest from 10 paces (25 feet) away with a 44. Caliber handgun, when it

A bullet proof vest consists of a vest-shaped panel made up of advanced plastic polymers that are composed of many layers of Kevlar or Spectra shield. The layers of Kevlar are sewn together using Kevlar thread but the nonwoven spectra shield is coated and bonded with resins such as Kraton and sealed between two sheets of Kevlar. Once all of the panels of Kevlar are sewn together it is placed inside of a fabric shell that is usually made from polyester and cotton blend or nylon. A bulletproof vest

In this week’s reflection assignment the required viewing material was a video that addressed the topic of hand swaging bullets. The video gave an overview of the projectiles themselves and also showed the method in which they are to be loaded. The video began by stating that the projectiles were sent to him to be tested and he did not swage the swaged projectiles that are being shown in the video. The projectiles were unique in the fact that the person that swaged them used a die that would allow

The forensic examinations I would perform are bullet stria examination, external ballistics, blackening, GSR testing, and ferrozine testing. Based on the stria of the rounds that can be recovered from the walls of the crime scene they can be matched to test rounds fired from the weapon to confirm they match. Stria can also be called striation marks. Stria or Striation marks are spiral lines left on the bullet and bullet casing. Stria on the bullet is formed by the barrel rifling when the weapon is

Bullet Comparison and Analysis The firearms and tool marks division of most forensic science laboratories have several tasks they may have to perform on items of evidence that come to them; this ranges from testing functionality of a weapon, restoring serial numbers, finding and comparing marks left from different tools at a crime scene, and comparing and analyzing bullets and casings. To be able to perform a bullet comparison, one needs to be able to distinguish several base class characteristics

plastic bullet alternative Imagine a world in which there is less plastic-based pollution, a healthier ecosystem, and cheaper gun ammunition. You have now pictured a world which uses an alternative material for gun ammunition: plastic. Plastic bullets are, or can be, forged, fired, and as effective as leading gun ammunition materials. Plastic, while non-renewable, can be recycled and reused in ways that were formerly unimaginable or perceived. Using recycled plastic in the process of bullet making

The 25 minute Magic Bullet infomercial is full of persuasion in many aspects. Throughout my paper I will highlight how the commercial uses Ranks Model of Persuasion, starting with the intensify and downplay strategies that I observed from watching the Magic Bullet Commercial. The strategies and tactics that the persuaders used worked well, by the end of the commercial I wanted the product they advertised. Throughout my paper I will go more in depth to Rank’s Model of persuasion by analyzing, explaining

One Bullet Away is a military memoir written by and about Nathaniel Fick’s terrifying journey through blood, sweat and tears in Iraq and Afghanistan. The story is divided into three parts: peace, war and aftermath. During the “peace” phase of the story Fick is introduced as the main character as he develops useful skills while going through military training. This part mainly takes place in Quantico, Virginia and San Diego, California. Taking up the majority of the story is the “war” phase. Even

and heavy bullets, there were three favorite choices. The first was a Winchester offering, WW296, a ball powder with a good burning rate and characteristics tailored for big revolver cartridges. The shape of the powder granules determines how well they pass through a given powder measure. The ball-shaped powders worked well through most powder measures, eliminating the need to weigh each and every charge, a time consuming step that anyone loading hundreds of rounds of ammunition per week would be

depending on how close or distant the shooter was from the victim or surface. Finally, at a crime scene an investigator must gather evidence at a death scene. When a handgun is used the investigator should document class characteristics of a firearm, bullet or shell casing. Also, the handgun or ammunition should be dusted for fingerprint and DNA evidence. Early handguns of the 14th century were made of a bronze tube or wrought iron, packed with gun powder and a projectile then ignited through a touch-hole
