Poly Throwing Rifling

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.

Problems resulted due to soft factory projectiles causing Glock to issue warnings against the use of lead. Many companies today will void a warranty if hand-loads are used and this is not economical for shooters. According to Campbell (2017 Pg-1), the Glock uses a unique form of rifling known as polygonal rifling. According to Nash (2012), in a polygonal barrel, these cut lands and grooves are replaced by “hills and valleys” in a more gently rounded polygonal pattern, usually a hexagon or

This weeks assignment covered a specific drum magazine and the Ruger 10/22 rotary magazine. Granted, they both are tried and tested feeding mechanisms, they both serve a particular role and share many similarities. At one point(first video) he mentioned the ergonomic characteristics for the X91 skeletonized drum opposed to the Beta drum. I found this portion somewhat insightful. I’ve personally used a Beta drum and it does bring the benefit of having a high capacity but is also cumbersome. The Beta drum takes away from the fluidity and speed from the shooter. I honestly have nothing against high capacity magazines, I just don’t see the benefits or value in having a drum. Most drums are used in fully automatic rifles for suppressive roles in

To date, we took, adapted, and modified the older rifling to modern rifling which have fairly sharp edges in a Polygonal shape. The grooves are the spaces that are cut out of the barrel, and the resulting ridges are called lands. The Polygonal rifled barrel tends to have longer service due to less fouling, debris, and erosion effecting the barrel. As the barrel adapted so did the propellant, thus we moved from packed powder to primed

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.)

After analyzing Ruvens football throw I noticed a lot of good things about the throw. One good thing I noticed was that his eyes were always on the receiver. During his drop back his eyes stayed glued on the receiver. This would allow him to make an accurate smart throw. Another good aspect of Ruvens throw was his weight shift. After his drop back Ruven was able to transfer his weight towards the receiver allowing him to put more power on his throw. One part of the throw that I noticed Ruven did well was holding the football by the bottom laces, which allowed him to have better control of the ball. Lastly, a good thing I noticed about Ruvens throw was how he flicked his wrist. After releasing the ball Ruven flicked his wrist. This allows the

This allowed the cylinder of the pistol to spin freely while in half cock, enabling the soldier/wielder to easily reload whenever he/she felt necessary. With such numerous advantages over the flintlock pistols , the Colt Revolver essentially revolutionized the way weapons were created and their mechanisms. In the current day, most firearms operate with a magazine which holds the bullets that are to be fired from the weapon. Similarly, in the Colt Revolver, there was a cylinder containing the bullets that were to be shot from the Revolver thereby maximizing the efficiency of weapons.

The U.S. civil war was the most bloody conflict that the U.S. had ever been involved in. It brought over 1,100,000 casualties from both sides, with over ninety percent of these casualties resulting from small- arms fire (Howey “Weaponry, the Rifle-Musket and the Minié ball”). The Minié Ball has been widely attributed to a majority of these cases. The Ball was a bullet developed by Claude-Étienne Minié and Henri-Gustave Delvigne in 1849 after the two French officers decided to improve on a currently existing design (HistoryNet “Minié Ball”). The pair also designed a rifle, a gun containing a barrel with grooves running in a corkscrew fashion along the length of the barrel. These grooves caught the bullet as it traveled down the barrel and spun it, greatly increasing the velocity and accuracy of the bullet as it left the barrel. Compared to the earlier musket balls, which bounced around in the barrel and exited at an unpredictable angle, it was much more accurate. When the bullet arrived in the United States, James Burton at the arsenal in Harper’s Ferry, Virginia, simplified the bullet into the .58 calibre widely used in the Civil War (Leonard “The Bullet That Changed History”). The ball, made of soft lead, featured a conical shape and a hollow center. This allowed it to expand to fit the barrel when shot out of the gun and easily engage the rifling, making it more aerodynamic and capable of flying at

Both are considered long guns because they are shot from the shoulder and held with two hands. One of the major differences between the two is the barrel. On a rifle the barrel has a thicker wall with a smaller bore and rifling. Rifling is a thin grove or ridges inside the bore to give a spin on the projectile, which increases accuracy and distance. Shotgun has a thinner wall with a smooth bore. Specialty shotguns may have a choke in the bore, which adds a narrowing about 1½ inch from the end of barrel, to control the shot as it leaves. Another option for a choke is a screw on choke. When using a screw on choke one must be cautious about using the correct threaded choke, such as a Remington choke with a Remington barrel. A second difference is rifles use a cartridge and shotgun uses shells. Cartridges are measured in calibers and shells are measured in gages, except .410gage, which is acutely a caliber and would be equivalent to 68gage. Both rifles and shotguns have different types actions, such as single shot, semi-automatic and

In the end, I ended up researching and finding an article that beautifully explains to non-model-making people why people make gunpla. From Scalemodelguide.com, some of the top reasons are:

A century after the matchlock was first recorded there was another incredible breakthrough in the field of Gunsmithing it was the wheel lock. This was a true innovation in firearm history this is the first firearm with rifling to increase accuracy. How this gun worked is when the trigger is pulled it spins a wheel that has rough steel and at the same time a hammer is lowered on to the spinning wheel causing sparks to ignite the powder in the flash pan in turn propelling the projectile out of the rifled barrel. The only disadvantage with this firing mechanism is the cost it was too expensive to produce very many.

In wars prior to the Civil War, soldiers wielded weapons such as the musket which shot only one bullet at a time. Though these types of weaponry could shoot as far as 250 yards, they were inconvenient and wasted time. To even aim at the target accurately one had to be 80 yards away. Similarly to muskets, rifles were inconvenient because they took a while to reload because the bullet was almost the same size of the barrel and again, wasted time. Bullets with a pointed tip were created in 1848 by Claude Minie. Because the diameter of the bullets were smaller than the barrel, soldiers could put them into the gun quicker and more effectively. With Minie’s bullets, rifles were simpler to reload but still had to be reloaded with one bullet at a time. That unprotected gap of time made soldiers more vulnerable so in 1849 a repeating rifle called the Volitional Repeater was patented by Walter Hunt. They were popularized in 1863 during the Civil War. By this time many models were being sold but the most common one was the Spencer Carbine which could shoot seven bullets in just 30 seconds. These, like most Civil War era weapons, were produced and used by the North, but not

Taming slug guns; this is a very interesting article to me as I have shot single barrel shotguns in my youth and know all too well how much they kick, however, I have never seen a shotgun with ported holes drilled in it to reduce the kick. This has truly opened my eyes to how there are so many ways to modify guns to fit the person using it. In my opinion, I would think that drilling holes in the top of the barrel would cause the gun to lose some power/distance of the projectile(s). By releasing gas out of the top of the barrel the pressure that is used to push the projectile down the barrel would lose velocity.

The barrel of the weapon had an octagonal upper portion with a rounded bottom and it had a black walnut stock. The stock of the weapon was also cracked indicating that it was damaged either before or directly after the assassination of President Lincoln. Booth’s derringer had an S-shaped trigger guard used to prevent accidental discharges. The weapon was made of brass and barely weighs eight ounces (Smith). To put that into perspective a can of soda typically weighs more. The rifling in the pistol was unique in the fact that it had seven grooves and rotated counterclockwise, whereas most derringer pistols from the time period contained clockwise rifling (Schehl). It fires a single lead ball roughly half an inch in diameter. The derringer used to kill Lincoln uses a percussion firing cap to fire the ball of lead that is less than half an inch in diameter. When fired blue grey smoke flows from the barrel leaving a unique signature. The total length of the derringer is about 5.87 inches and can easily fit into someone’s pocket (Slomski). Because of the weapons size it was often called a gentleman’s or ladies pistol, as it was used for self-defense. The size and weight of the weapon make it easy to conceal and carry making it the perfect weapon for Booth to use in his assassination plot.
