Mortars are typically classified by their caliber (diameter of the bore) and are used by military forces for a variety of purposes, including indirect fire support, counter-battery operations, and area bombardment.
"Caliber" can refer to several different concepts depending on the context. Here are a few common interpretations: 1. **Measurement**: In a general sense, "caliber" refers to the diameter of a cylindrical object, often used in the context of firearms to indicate the diameter of the gun's barrel or the projectile (bullet) it fires. For example, a .38 caliber revolver fires a bullet that is .38 inches in diameter.
A cartridge box is a container used to hold cartridges, which are devices that contain a projectile (such as a bullet), propellant, and primer. Historically, cartridge boxes were used extensively during the 19th and early 20th centuries, particularly in military contexts, to store and transport ammunition for rifles, pistols, and other firearms. Cartridge boxes could be made from various materials, including wood, metal, leather, or canvas.
Rimmed cartridges are a type of ammunition characterized by a pronounced, raised lip or rim around the base of the cartridge case. This rim is wider than the diameter of the cartridge body and serves several purposes: 1. **Extraction**: The rim aids in the extraction of the cartridge from the chamber after firing. When the firearm is operated, the extractor rod can catch the rim, pulling the spent cartridge case out of the chamber.
Shotgun shells are a type of firearm ammunition designed specifically for shotguns. They consist of a cylindrical casing that contains several components: 1. **Casing:** The outer shell, typically made of plastic or paper, holds all the other components together. 2. **Primer:** Located at the base of the shell, the primer ignites the gunpowder when struck by the firing pin.
The term "105 mm caliber" typically refers to the diameter of a projectile, specifically a shell or artillery round, that measures 105 millimeters across. This caliber is commonly associated with various types of military artillery, tank guns, and howitzers. One of the most notable examples of a 105 mm artillery system is the M101 howitzer, which has been widely used by various military forces around the world.
The term "11.3×36mmR" refers to a specific type of ammunition, particularly a type of rimmed cartridge. 1. **Caliber**: The "11.3" in the name indicates that the bullet diameter is approximately 11.3 millimeters, which is roughly equivalent to .445 inches. 2. **Length**: The "36mm" indicates that the cartridge case is 36 millimeters long.
The term "120×570mm NATO" refers to a specific type of ammunition used for tank cannons, most notably the smoothbore cannon found in modern main battle tanks, such as the Leopard 2 and the M1 Abrams. Here's a breakdown of the terminology: - **120 mm**: This indicates the caliber of the projectile, which is 120 millimeters in diameter.
The term "Dirty Harry round" typically refers to the .44 Magnum cartridge, which was popularized by the character Harry Callahan, played by Clint Eastwood in the film "Dirty Harry" (1971). In the movie, Harry Callahan famously refers to his .44 Magnum as "the most powerful handgun in the world," highlighting its significant stopping power and effectiveness for law enforcement and self-defense at the time. The .
Fire forming is a technique used primarily in firearms and reloading to shape or resize brass cartridge cases to fit a specific chamber more precisely. During this process, a casing is fired in a specific firearm, which allows the brass material to expand and conform to the dimensions of the chamber. ### Key Points about Fire Forming: 1. **Purpose**: The primary goal is to create a cartridge case that perfectly matches the chamber of a particular firearm, improving accuracy and efficiency by ensuring a tighter fit.
Obturation is a term that can refer to different concepts depending on the context in which it's used. Here are a couple of its common meanings: 1. **In Dentistry**: Obturation refers to the process of filling the root canal of a tooth after root canal treatment. The objective is to seal the canal to prevent re-infection and to restore the tooth's function.
The 2008–2016 United States ammunition shortage refers to a significant and prolonged scarcity of ammunition that occurred in the U.S. during those years. Several factors contributed to this shortage: 1. **Increased Demand**: The election of Barack Obama as President in 2008 led to a surge in gun sales and, subsequently, ammunition purchases. Many gun owners feared potential restrictions on firearms and ammunition, prompting them to stockpile supplies.
The 2020–present United States ammunition shortage refers to a significant and ongoing scarcity of ammunition in the U.S. that began around early 2020 and has continued for several years. Several factors have contributed to this shortage: 1. **COVID-19 Pandemic:** The onset of the pandemic led to increased demand for firearms and ammunition as people sought to protect themselves and their families. This surge in demand coincided with disruptions in manufacturing and supply chains caused by lockdowns and factory closures.

Pinned article: Introduction to the OurBigBook Project

Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
We have two killer features:
  1. topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculus
    Articles of different users are sorted by upvote within each article page. This feature is a bit like:
    • a Wikipedia where each user can have their own version of each article
    • a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
    This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.
