Cartridge And Firearms Identification Paper

An investigation involving a firearm is a specialty of forensic science which focuses on the examination of firearms linked to ballistics. Ballistics is related to finding out the exact flight path of projectiles. Ballistics is the area of study that examines the exact path of the bullet from the moment it leaves the muzzle of the firearm up until it hits the target. During examination many items are collected for evidence including the firearm, bullets, live ammunition, cartridge casings, trace materials such as powder residue, and anything damaged by the projectile. Firearms are often divided into three processes: Internal, External, and Terminal Ballistics. Internal refers to the inside of the firearm; the space of time in which the shooter pulls the trigger, and the when the bullet is exiting. External ballistics is the flight between leaving the muzzle of the firearm, and it striking its target. Terminal ballistics is the impact of ballistics that refers to the examination in which the projectile strikes a target. All firearms leave markings on the cartridge casings once expelled when firing. Ballistic identification and microstamping laws make it possible to link a cartridge recovered to the

IntroI am doing this report on the M1 Garand for Mr.Walker 182's History Class. The Garand is a fascinating World War II semi-automatic rifle. In the sub-sections below I will describe the developement history of the gun, the service history, and info on different versions. I wanted to add diagrams of the M1 rifle but the pictures are copyrighted and I was not able to download but the diagrams could be found at <a href="http://www.chestnutridge.com/gchart.asp">http://www.chestnutridge.com/gchart.aspDevelopment HistoryThe origins of the United States Rifle, Caliber .30, M1 begin around August, 1900, when Captain O.B.

If it doubt, do not dust for prints, submit in person to the laboratory and request that the firearm be processed for prints. After processing the scene, the evidence should be sent to the laboratory, personal delivery is preferred. A loaded handgun may be transported in a specially constructed box which has a means of securely holding the firearm and has a metal plate blocking the muzzle. If the firearm is to be sent by mail it must be unloaded and securely packaged. At the end, make a sketch of the area which shows the location of each evidence item collected. The sketch should contain location measurements which reference each evidence item to a fixed object or a reference point. Photographs should be used to supplement notes and sketches, but not as a substitute for them. For later identification the serial number of a firearm should be recorded. Some older rifles and shotguns, may not have a serial number. If the firearm is marked for identification by scribing, the marks should be placed in a location where they will not damage the appearance or value of the

This paper explores deoxyribonucleic acid (DNA) collection and its relationship to solving crimes. The collection of DNA is one of the most important steps in identifying a suspect in a crime. DNA evidence can either convict or exonerate an individual of a crime. Furthermore, the accuracy of forensic identification of evidence has the possibility of leaving biased effects on a juror (Carrell, Krauss, Liberman, Miethe, 2008). This paper examines Carrells et al’s research along with three other research articles to review how DNA is collected, the effects that is has on a juror and the pros and cons of DNA collection in the Forensic Science and Criminal Justice community.

A Rifle could shoot a bullet up to 1,000 yards–and were more accurate. However, until the 1850s it was nearly impossible to use these guns in battle because, since a rifle’s bullet had roughly the same diameter as its barrel, they took too long to load. (Soldiers sometimes had to pound the bullet into the barrel with a mallet.)

The history of firearms has changed dramatically since the late 1700’s. A rifle is no longer defined as a single shot, muzzle loading musket. Should

One of the handguns used during WWI by the United States was the M1917 Revolver. The production of this revolver started in 1917 and spanned into 1920, and it remained in service until 1954. The barrel if the gun was a standard 5.5 inches while the revolver had an overall length of 10.8 inches. (Colt Model 1917) There

When the constitution was written the most advanced gun only shot one bolt at a time, and took 30 seconds to reload (Murphy). Now in the 21th century guns have “high-capacity magazines were used in at least 50% of the 62 mass shootings between 1982 and 2012. When high-capacity magazines were used in mass shootings, the death rate rose 63% and the injury rate rose 156%. David H. Chipman...stated that a high-capacity magazine ‘turns a killer into a killing machine.’ Some gang members use high-capacity magazines, such as 30 rounds or even 90 rounds, to compensate for lack of accuracy and maximize the chance to harm” (“Background of the Issue - Gun

A firearm is a very complex tool that has grown in s verbal ways over several years, each version better than the last, all of which changing the world in a new way.All across the world and across several eras firearms have been used, firearms have also been the reason for wars and laws, as a very important part of our history it is appropriate that several facts are clearly stated.Back in the Han dynasty, under the leadership of emperor Wu Di, gunpowder was discovered. This particular document will include such topics such as the one previously stated and early firing systems and other weapons, also a brief history of military issued pistols through America's history and your rights as an american citizen to bear arms. Firearms, from early

By 1863 the importation of foreign arms had stopped except for fulfilling contracts on Enfield rifles. By this time the domestic production of Springfield’s

Throughout history the United States Army has undergone a plethora of changes. Since its inception in 1776 ever this has evolved from personnel, to rank structure, even the uniforms but the one piece of equipment that has seen the most change has been the weaponry; more specifically the small arms issued to individual soldiers. Small arms used by American forces in the Revolution were many and varied, however at the beginning of the war the British Short Land Service Musket, often referred to as the Brown Bess, was perhaps the most common musket on hand. In 1777, the French allied themselves with the American cause and began sending arms and equipment. After the revolutionary War the Army transitioned to The U.S. Musket Model 1795 this rifle

With the recent announcement by the Federal Bureau of Investigation that they will be going back to the 9mm cartridge, there has been a rekindling of the age old caliber war on various internet forums and on social media sites such as FaceBook. It so happens that this new round of my caliber is better than your caliber comes at a time when I am making preparations to attend the 2015 Realistic Advanced Combatives Seminar hosted by Cabelas in Dundee, Michigan and taught by Dave Spaulding and Sgt. Charles E. Humes.

Processing all different types of firearms is as important as lifting a fingerprint or packaging DNA as evidence. It must be done in a cautious, & safe manner so that fingerprints are not ruined, & safety of the investigator is insured. While using the proper techniques to processing firearms for evidence a case can be brought to closure quicker, & another criminal can be removed from the streets. The investigators must realize the importance of the firearm being processed in order to find clues that lead to a suspect, therefore collecting evidence should be error free for an example such as not having the correct bullet casing at a shooting, can be in favor of the suspect.

In the past 150 years or so there has been a tremendous amount of development in the evolution of the cartridge. The Henry .44 Henry rimfire cartridge has been proven as the stepping stone to the modern day rimfire cartridges. It’s creator B Taylor Hennery first developed the rimfire for a project with the New Arms Company when he was tasked to redesign a new action for the Volcanic Rifle. Henry later developed the .44 flat cartridge which caught the attention of Oliver Winchester who wanted to develop a repeating firearm, which lead to the development of the Winchester Model 1866 lever action. To this day, Winchester still pay homage to the founder of the rimfire cartage by placing a H on heads of all its rimfire cartridges.

The .22 caliber small diameter projectile was one of the first small diameter projectiles introduced and has been developed and adapted for over a century becoming the most popular small bore caliber in history. While most shooters automatically jump to .22 LR when they hear .22 caliber, however there are hundreds of variations of the .22 caliber loadings and cartridges. The .22 Short rimfire cartridge is one of the longest running .22 caliber cartridges still in production, it was introduced in 1857 for use in a Smith & Wesson revolver1. This development went on to lead to the .22 long, .22 extra long and a whole lineage of .22 caliber rimfire cartridges all the way to the .22 WMR in 1959, another very popular .22 rimfire design that has recently been giving the .22LR a run for its money. The .22 caliber bullet continued on to be developed into centerfire
