namely the inventions of the Minié ball, the Spencer and Henry repeating rifles, and of the Gatling gun. Prior to the invention of the Minié ball it was necessary for the bullet to be the same diameter as the barrel in order for it to engage the rifling. This made it difficult and time consuming to load because the bullet would have to be rammed down the barrel with some force. Due to this fact, muzzle loading rifles had not seen any previous use in combat. The Minié ball, however, changed this
this essay deals with the flight of the bullet, terminal ballistics will not be discussed. Internal ballistics is the study of the flight of a projectile inside the firearm. The main components of internal ballistics include the firing process, rifling, and recoil. The Firing Process The firing process begins when the trigger of a gun is pulled. This releases the firing pin, allowing it to collide with and ignite the primer and cartridge. As the cartridge burns, it produces a hot gas that
How Guns Work A gun is a weapon that uses the force of an explosive propellant to project a missile. Guns or firearms are classified by the diameter of the barrel opening. This is known as the calibre of the gun. Anything with a calibre up to and including . 60 calibre(0.6 inches) is known as a firearm. The precise origin of the gun is unknown, although they were in use by the early 14th century and were common place in Europe by mid-century. These early guns were nothing more than large calibre
Firearm and Tool Mark Analysis is exactly what it sounds like – a compilation of those two separate sciences. They have come to be associated together because by practicing one of those skills, the person generally will have the knowledge and intuition to practice the other. By definition, firearms identification is a discipline mainly concerned with determining whether a bullet or cartridge was fired by a particular weapon (Saferstein, 460). A tool mark is any impression, cut, gouge, or abrasion
The .243 Winchester (6×52mm) is a popular sporting rifle cartridge. Initially designed as a target/varmint round, it may be used for animals such as coyote, blacktail deer, whitetail deer, mule deer, pronghorn, and wild hogs. It can also be used against larger animals such as black bear or elk but is sometimes said to be "too light" for such large animals. Rounds of at least 90 grains are better suited for hunting larger animals while rounds less than 90 grains are more suitable for varmints.[3]The
In 1784, someone using a flintlock pistol shot Edward Culshaw. In those days, there were no bullets, as we know them. Gunpowder and a ball of lead were put into the gun’s muzzle and packed with paper wadding. A spark made when the gun’s hammer struck some flint at the back end of the barrel ignited the powder. When the constable examined Culshaw’s wound, he found a piece of newspaper used as wadding to pack the powder in the killer’s gun. The prime suspect in the killing was a man named John Toms
Weapons in the American Civil War The American Civil War is known to be one of the bloodiest wars in history. Significant advances in weapon technology contributed to the unprecedented carnage. All types of weapons were being invented including side arms, shoulder arms, and artillery. Surveying the origins and design of only a portion demonstrates fire power had outstripped battlefield tactics by the mid-nineteenth century. Side arms, most useful only at close range, underwent important changes
Smith & Wesson is very efficient at the manufacturing of firearms. Smith & Wesson’s new handgun will be manufactured in different stages. The individual parts are manufactured at different times and in different places. The barrels and frames are manufactured in their main Springfield plant. The rest of the pieces are then brought to the Springfield plant to be manufactured and shipped. The assembly of the entire handgun should take less than an hour, start to finish. This should be close to
cocking the hammer. This concept made the five shooter the first practical, fast-firing repeaters when they came out of his Paterson, New Jersey, factory in 1836.” As the author explains this technology was important evolutionary change for firearms, not did it implement the more reliable way of igniting the charge in a guns barrel, the percussion cap, but it allowed for a more rapid and sustained rate of fire which would become very important. This technology of repeating sustained fire rate would
The Civil War was a period of great social and political change. It was additionally a period of great mechanical change. Inventers and military men conceived new sorts of weapons, for example, the rehashing rifle and the submarine, which always showed signs of change the way that wars were battled. Significantly more vital were the advancements that did not particularly need to do with the war, similar to the railroad and the broadcast. Advancements like these did not simply change the way individual’s
The M16 With its light weight of less than six pounds and its powerful ammunition, small 5.56mm circumference, short 38.80 inch long body, a whipping 3,250 feet per second muzzle velocity, and a maximum efficiency range of 460 meters the M16 is the most versatile standard issue rifle of any army. You may think that the brains of the government's army may have devised the plan to make the M16, but it was none other than the brains of John Hopkins University where the development of
The Spencer Repeating Rifle Was designed in 1860 by Christopher Spencer. Christopher Spencer was born 1833 and died in 1922. He was born in Manchester, Massachusetts. He was a machinist in Hartford, Connecticut. He designed and build the Spencer Repeater. The Spencer Repeater is a rifle. A rifle is a gun, especially one fired from shoulder level, having a long spirally grooved barrel intended to make a bullet spin and thereby have greater accuracy over a long distance. A rifle is a firearm designed

Rifles For Watie: Weapons of the Civil War Many weapons were used during the Civil War. Some definitely saw more use than others, and some may have been forgotten. The most popular weapon used in the Civil War was most likely the Spencer Repeating Rifle. The Spencer Repeating Rifle replaced the much less effective musket. A less popular weapon, for example, were landmines, and were deemed as barbarous and banned for use. The less popular, maybe even “unusual” weapons, vary greatly in use
because of its effectiveness, shooting bullets straight and accurate because of the aerodynamics and physics of the spiral motion with the bullet. What makes the rifle a rifle and much better than a musket, is the fact that it has rifling throughout the barrel of the gun. Rifling is a system of spiral grooves in the surface of the bore of a gun causing a projectile when fired to rotate about its longer axis (Merriam-Webster). The rifle changed America by starting long range warfare, enforcing a new industry
Many weapons were developed for the sole cause of winning world war one. Empires had to push forward military technology to gain the upper hand in war. Many of these weapons were seen as cruel and unnecessary as they put soldiers through pain and agony before finally killing them. Although these weapons were notorious for how they were used, not many people know how important they were to drive the war forward. Although weapons were necessary to win the war, so were countermeasures. As new killing
Safe handling of firearms at crime scene. A high priority at a crime scenes safety in collecting the firearm. Preservation of evidence is essential. The firearm used to commit the crime may not be at the scene, cartridge casings and expended projectiles may be at crime scene and provide information about the type of firearm used. When a firearm is retrieved by a suspect it can be identified by distinctive tool marks on the expended casings, and individuals bullets can be linked to the firearm. By
marks left behind, one can scientifically prove the kind of weapon used, trajectory and estimate the distance between criminal and victim. To begging with, there are a variety of firearms and they all come in different sizes, shapes and different rifling marks. An example of firearms are semiautomatic pistols, according to Young
