.577 Tyrannosaur
The .577 Tyrannosaur or .577 T-Rex (14.9×76mm) is a very large and powerful rifle cartridge developed by A-Square in 1993 on request for professional guides in Zimbabwe who escort clients hunting dangerous game. The cartridge is designed for use in "stopping rifles" intended to stop the charge of dangerous game. The cartridge contains a diameter monolithic solid projectile which when fired moves at producing of muzzle energy Muzzle energy is the kinetic energy of a bullet as it is expelled from the muzzle (firearm), muzzle of a firearm. Without consideration of factors such as aerodynamics and gravity for the sake of comparison, muzzle energy is used as a rough indi .... The production model from A-square was based on their Hannibal rifle. A-Square is defunct as of 2012.

Cartridge (firearms)
A cartridge, also known as a round, is a type of pre-assembled firearm ammunition packaging a projectile ( bullet, shot, or slug), a propellant substance ( smokeless powder, black powder substitute, or black powder) and an ignition device ( primer) within a metallic, paper, or plastic case that is precisely made to fit within the barrel chamber of a breechloading gun, for convenient transportation and handling during shooting. Although in popular usage the term "bullet" is often used to refer to a complete cartridge, the correct usage only refers to the projectile. Military and commercial producers continue to pursue the goal of caseless ammunition. Some artillery ammunition uses the same cartridge concept as found in small arms. In other cases, the artillery shell is separate from the propellant charge. A cartridge without a projectile is called a '' blank''; one that is completely inert (contains no active primer and no propellant) is called a '' dummy''; one that ...

A-Square
A-Square Company, LLC was a manufacturer of rifles, ammunition and bullets based in Chamberlain, South Dakota, in the United States. The company was one of 19 that are members of the SAAMI, Sporting Arms and Ammunition Manufacturer's Institution (SAAMI). The company's focus was on its firearms for hunting large dangerous game. This was reflected in the selection of larger caliber chamberings in the company's rifles. History The company was established in 1979. Lieutenant Colonel Arthur Alphin, Arthur B. Alphin was the founder and chief designer for the A-Square Company. Besides the company location in Chamberlain, South Dakota, the company had a location in Bedford, Kentucky. By August 2008 Alphin planned to move his ammunition factory to Butte, Montana. A-Square-manufactured rifles usually came with stainless steel barrels as a standard feature. The barrels on the rifles use epoxy resin to bed the barrel to the stocks. Magazine boxes were manufactured from plate steel for rigi ...

The capital and largest city is Harare, and the second largest is Bulawayo. A country of roughly 16.6 million people as per 2024 census, Zimbabwe's largest ethnic group are the Shona people, Shona, who make up 80% of the population, followed by the Northern Ndebele people, Northern Ndebele and other #Demographics, smaller minorities. Zimbabwe has 16 official languages, with English, Shona language, Shona, and Northern Ndebele language, Ndebele the most common. Zimbabwe is a member of the United Nations, the Southern African Development Community, the African Union, and the Common Market for Eastern and Southern Africa.

Muzzle Energy
Muzzle energy is the kinetic energy of a bullet as it is expelled from the muzzle (firearm), muzzle of a firearm. Without consideration of factors such as aerodynamics and gravity for the sake of comparison, muzzle energy is used as a rough indication of the destructive potential of a given firearm or cartridge. The heavier the bullet and especially the Muzzle velocity, faster it moves, the higher its muzzle energy and the more damage it will do. Kinetic energy The general formula for the kinetic energy is E_\mathrm = \frac mv^2, where ''v'' is the velocity of the bullet and ''m'' is the mass of the bullet. Although both mass and velocity contribute to the muzzle energy, the muzzle energy is proportional to the mass while proportional to the ''square'' of the velocity. The velocity of the bullet is a more important determinant of muzzle energy. For a constant velocity, if the mass is doubled, the energy is doubled; however, for a constant mass, if the velocity is doubled, the ...
