Rifling

tells us that, “ A casualty is a military person lost through death, wounds, injury, sickness, interment, capture, or missing in action.” The Civil War was another war fought on American soil for freedom. The Civil War used the new technology of rifling and minié ball and it was revolutionary. The Civil War was fought over a four year span and accumulated right around six hundred and twenty thousand casualties. This was devastating; the new technology was important to the advancement of firearm technology

inside the barrel of a Glock and other barrels of the polygonal rifling type. What is a polygonal rifling? The best way to explain it as it relates to firearms is, in a rifling there is slight rise in the rifling and tighter twist in the barrel. The befit from the polygonal rifling is less bullet deformation, higher average velocity and a bore that is easier to clean. Alongside polygonal rifling, the bullet grips tighter to the rifling and creates a tighter gas seal. The disadvantage of a polygonal

reasons as to why weapons have become more accurate is because of rifling in the barrel. Rifling of the barrel is grooves down the interior of the barrel which puts a spin on the bullet as it leaves the end of the barrel thus stabilizing the bullet while it is on its way to the target. After people had rifled the barrel they found that a rifle was much better at hitting the target over longer distances (Supica). One major thing that rifling helped was wars. The rifles used in the Revolutionary War, flintlock

The NIBIN is a network that provides law enforcement agencies around the world with access to the images and information. 2. What is rifling? What two types of markings does this produce? A rifling is a given spiral grooves by the manufacturer. This rifling or spiral grooves cut into the barrel of a gun in order to make a bullet spin as it is fired. Rifling produces grooves and lands. 3. What is a distance determination? How is this done? A distance determination is the process of estimating

NIBIN? NIBIN is the National Integrated Ballistic Identification Network that was created by the FBI and the ATF in 1999. 2. What is rifling? What two types of markings does this produce? Rifling is when each gun is given spiral grooves by the manufacturer. The spiral grooves are cut into the barrel of a gun in order to make a bullet spin as it is fired. Rifling produces grooves and lands. 3. What is a distance determination? How is this done? A distance determination is the process of estimating

HISTORY OF FIREARMS Firstly, for a clear understanding the history of firearms is extensively complicated and the actual fact is that the scientific approach was often discovered well before they had a practical use. The discovery of gunpowder by the Chinese over a thousand years ago led to the evolution of firearms though it was predominantly used in firecrackers and nothing more besides in some weapons for military purpose. Gunpowder is commonly made up of Charcoal, Sulphur and Saltpetre( Potassium

document the condition of the packaging and of the evidence received. The first step of the actual comparison, is determining the general rifling characteristics, or the class characteristics. Most fired projectiles will be able to tell an examiner the caliber of the barrel, the number and dimensions of the lands and grooves, and the direction of the twist of the rifling (“A Simplified Guide,” 2013). The caliber of the barrel of the gun is the “diameter of the bore of a rifled firearm,” usually measured

Some say that war never changes. That in the end, it is always the same, a time where conflict took the better of humanity. They take a look at the big picture, but never take the time to look at the pieces that compose it. War is a constantly evolving puzzle, where new pieces are constantly being added, making the puzzle more complicated every time. With every new era comes new tools. In the American Civil War, a country divided against itself will see warfare like never before, from repeating rifles

Weapons of War During the Civil War, there were many weapons used, that played a big role in the civil war and how it shaped America. The war brought great trials and tribulations as it came to the development of new war weapons and blockades that gave each side a higher rank as it came to the deciding of the civil war. During this war, both sides had an upper hand when it come to the weapons they used and the several tactics they used to ambush and attack the enemy. There were many essential weapons

pressure produced from the burning of gunpowder to create gas. The pressure produced from the burning powder propels a projectile out of the barrel at a target. In rifles and most handguns the barrel has rifling on the inside of the barrel to make the projectile spin to travel better in the air. Rifling are groove that spin as they go through the inside of the barrel. Shotgun barrels are smooth and can fire “slugs”, a single projectile, or “shot”,
