.240 Weatherby Magnum
The .240 Weatherby Magnum was developed in 1968 by Roy Weatherby. In the development of his own .240in/6 mm cartridge, Weatherby was significantly influenced by both the success and the limitations of the .244 H&H Magnum cartridge devised in England by his friend and colleague David Lloyd. It was the last cartridge to be designed by Roy Weatherby. Design The .240 Weatherby Mag. is a proprietary cartridge used only in Weatherby rifles. This particular Weatherby case is unique: other than shape, it isn't physically based on other Weatherby cases, having the same rim diameter and a similar length to the .30-06. It utilizes the traditional Weatherby rounded double shoulder and a belted case with a length of 2.496in, significantly shorter than the 2.8in case of the .244 H&H Mag. Performance In terms of velocity, the .240 Weatherby Magnum was once the fastest commercially produced 6 mm cartridge. There were several faster wildcat rounds available, but the .240 Wby. Mag. outclasse ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Roy Weatherby
Roy Edward Weatherby (4 September 1910 — 4 April 1988), was the founder and owner of Weatherby, Weatherby, Inc., an American rifle, shotgun and cartridge manufacturing company founded 1945. Weatherby created an entire line of custom cartridges, and was one of the people responsible for the industry interest in high-speed cartridges. He created a custom rifle action to accommodate his high-pressure cartridges. History He grew up on a farm in Kansas. He later moved to Huntington Park, California where he and his wife, Camilla, bought a Spanish style home located on 7672 California Street on the corner of Grand Avenue. Weatherby started manufacturing Weatherby Guns in his garage at the Huntington Park home. Weatherby firearms are best known for their very high-powered rifle cartridges, all bearing the name Weatherby#Calibers, Weatherby Magnum such as the .257 Weatherby Magnum (designed in 1944), the .378 Weatherby Magnum (1953) and the .460 Weatherby Magnum (1957), and for the pr ...

Foot Pounds
The foot-pound force (symbol: ft⋅lbf, ft⋅lbf, or ft⋅lb ) is a unit of work or energy in the engineering and gravitational systems in United States customary and imperial units of measure. It is the energy transferred upon applying a force of one pound-force (lbf) through a linear displacement of one foot. The corresponding SI unit is the joule. Usage The foot-pound is often used to specify the muzzle energy of a bullet in small arms ballistics, particularly in the United States. The term ''foot-pound'' is also used as a unit of torque (see ''pound-foot (torque)''). In the United States this is often used to specify, for example, the tightness of a fastener (such as screws and nuts) or the output of an engine. Although they are dimensionally equivalent, energy (a scalar) and torque (a Euclidean vector) are distinct physical quantities. Both energy and torque can be expressed as a product of a force vector with a displacement vector (hence pounds and feet); energy i ...

Weatherby Magnum Rifle Cartridges
Weatherby, Inc. is an American gun manufacturer founded in 1945 by Roy Weatherby. The company is best known for its high-powered magnum cartridges, such as the .257 Weatherby Magnum, .270 Weatherby Magnum, .300 Weatherby Magnum, .340 Weatherby Magnum and the .460 Weatherby Magnum. The company's headquarters is based in Sheridan, Wyoming. History The original production rifles by Roy Weatherby were built on commercial Mauser actions manufactured by FN, Brevex (magnum), and Mathieu (left hand). Weatherby would build a custom rifle from a customer's specifications for bespoke rifles, using any action the customer requested - provided the action was strong enough to tolerate the pressures for their desired cartridge. Weatherby manufactured his rifles for many years at his small facility in South Gate, California, until 1956, when he contracted with Sako to continue building his firearms based on the Weatherby-FN Mauser actions. Weatherby still produced some custom rifles in Sout ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Table Of Handgun And Rifle Cartridges
This is a table of selected pistol/submachine gun and rifle/machine gun cartridges by common name. Data values are the highest found for the cartridge, and might not occur in the same load (e.g. the highest muzzle energy might not be in the same load as the highest muzzle velocity, since the bullet weights can differ between loads). Legend * Factory loadings. Number of manufacturers currently producing complete cartridges - e.g. Norma, RWS, Hornady, Winchester, Federal, Remington, Sellier & Bellot, Prvi Partizan.

Grain
A grain is a small, hard, dry fruit (caryopsis) – with or without an attached hull layer – harvested for human or animal consumption. A grain crop is a grain-producing plant. The two main types of commercial grain crops are cereals and legumes. After being harvested, dry grains are more durable than other staple foods, such as starchy fruits (plantains, breadfruit, etc.) and tubers ( sweet potatoes, cassava, and more). This durability has made grains well suited to industrial agriculture, since they can be mechanically harvested, transported by rail or ship, stored for long periods in silos, and milled for flour or pressed for oil. Thus, the grain market is a major global commodity market that includes crops such as maize, rice, soybeans, wheat and other grains. Grains and cereal Grains and cereal are synonymous with caryopses, the fruits of the grass family. In agronomy and commerce, seeds or fruits from other plant families are called grains if they resemble c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
