.270 Weatherby Magnum
The .270 Weatherby Magnum was the first belted magnum based on the .300 H&H Magnum to be developed by Roy Weatherby in 1943. The cartridge is short enough to function in standard-length long actions with a brass length of 2.549" or 64.74mm and an overall length of about 3.295". History and design The development of the .270 Weatherby Magnum led to the characteristic double-radius shoulders belted magnum case, proprietary of the Weatherby Magnum line of cartridges. Particularly, the .270 Wby Mag the result of necked down to accommodate the .277 in bullets and bringing down the case to fit a standard length action. Like most Weatherby cartridges, the .270 Weatherby was standardized by the Small Arms and Ammunitions Manufacturers Institute in 1994, and it has a SAAMI maximum pressure limit of 62,500 psi. The first Weatherby cartridge to be used in Africa was the .270 Weatherby on a jackal on June 8, 1948. Performance Given its higher pressure and larger case which holds more pow ...

Roy Weatherby
Roy Edward Weatherby (4 September 1910 – 4 April 1988), was the founder and owner of 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 Magnum such as the .257 Weatherby Magnum (designed in 1944), the .378 Weatherby Magnum (1953) and the .460 Weatherby Magnum (1957), and for the production of appropriately- ...

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 ...

270 Weatherby Magnum
7 (seven) is the natural number following 6 and preceding 8. It is the only prime number preceding a cube. As an early prime number in the series of positive integers, the number seven has symbolic associations in religion, mythology, superstition and philosophy. The seven classical planets resulted in seven being the number of days in a week. 7 is often considered lucky in Western culture and is often seen as highly symbolic. Evolution of the Arabic digit For early Brahmi numerals, 7 was written more or less in one stroke as a curve that looks like an uppercase vertically inverted (ᒉ). The western Arab peoples' main contribution was to make the longer line diagonal rather than straight, though they showed some tendencies to making the digit more rectilinear. The eastern Arab peoples developed the digit from a form that looked something like 6 to one that looked like an uppercase V. Both modern Arab forms influenced the European form, a two-stroke form consisting of a ho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Pronghorn
The pronghorn (, ) (''Antilocapra americana'') is a species of artiodactyl (even-toed, hoofed) mammal indigenous to interior western and central North America. Though not an antelope, it is known colloquially in North America as the American antelope, prong buck, pronghorn antelope, and prairie antelope, because it closely resembles the antelopes of the Old World and fills a similar ecological niche due to parallel evolution. It is the only surviving member of the family Antilocapridae. During the Pleistocene epoch, about 11 other antilocaprid species existed in North America, many with long or spectacularly twisted horns.Smithsonian Institution. North American MammalsPronghorn ''Antilocapra americana'' Three other genera ('' Capromeryx'', '' Stockoceros'' and '' Tetrameryx'') existed when humans entered North America but are now extinct. The pronghorn's closest living relatives are the giraffe and okapi. See Fig. S10 in Supplementary Information. The antilocaprids are part of ...

Deer
A deer (: deer) or true deer is a hoofed ruminant ungulate of the family Cervidae (informally the deer family). Cervidae is divided into subfamilies Cervinae (which includes, among others, muntjac, elk (wapiti), red deer, and fallow deer) and Capreolinae (which includes, among others reindeer (caribou), white-tailed deer, roe deer, and moose). Male deer of almost all species (except the water deer), as well as female reindeer, grow and shed new antlers each year. These antlers are bony extensions of the skull and are often used for combat between males. The musk deer ( Moschidae) of Asia and chevrotains ( Tragulidae) of tropical African and Asian forests are separate families that are also in the ruminant clade Ruminantia; they are not especially closely related to Cervidae. Deer appear in art from Paleolithic cave paintings onwards, and they have played a role in mythology, religion, and literature throughout history, as well as in heraldry, such as red deer that app ...

Caliber
In guns, particularly firearms, but not #As a measurement of length, artillery, where a different definition may apply, caliber (or calibre; sometimes abbreviated as "cal") is the specified nominal internal diameter of the gun barrel Gauge (firearms), bore – regardless of how or where the bore is measured and whether the finished bore matches that specification. It is measured in inches or in millimetres, millimeters]ref name=barnes2016-p9> In the United States it is expressed in hundredths of an inch; in the United Kingdom in thousandths; and elsewhere in millimeters. For example, a US "45 caliber" firearm has a barrel diameter of roughly 0.45 inches (11.43mm). Barrel diameters can also be expressed using metric dimensions. For example, a "9 mm pistol" has a barrel diameter of about 9 millimeters. Since metric and US customary units do not convert evenly at this scale, metric conversions of caliber measured in decimal inches are typically approximations of the precise spe ...

Handloading
Handloading, or reloading, is the practice of making firearm cartridges by manually assembling the individual components ( metallic/ polymer case, primer, propellant and projectile), rather than purchasing mass-assembled, factory-loaded commercial ammunition. (It should not be confused with the reloading of a firearm ''with'' cartridges, such as by swapping detachable magazines, or using a stripper clip or speedloader to quickly insert new cartridges into a magazine.) The term ''handloading'' is the more general term, and refers generically to the manual assembly of ammunition cartridges. ''Reloading'' refers more specifically to handloading using previously fired cases and shotshells. The terms are often used interchangeably however, as the techniques are largely the same, whether the handloader is using new or recycled components. The differences lie in the initial preparation of cases or shells — new components are generally ready to load straight out of the box, w ...

Varmint Hunting
Varmint hunting or varminting is the practice of hunting vermin — generally small/medium-sized wild mammals or birds — as a means of pest control, rather than as games for food or trophy. The targeted animals are culled because they are considered economically harmful pests to agricultural crops, livestocks or properties; pathogen-carrying hosts/ vectors that transmit cross-species/ zoonotic diseases; or for population control as a mean of protecting other vulnerable species and ecosystems. The term "varminter" may refer to a ''varmint hunter'', or describe the hunting equipments (such as a varmint rifle) either specifically designed or coincidentally suitable for the practice of varmint hunting. Varmint hunters may hunt to exterminate a nuisance animal from their own property, to collect a bounty offered by another landowner or the government, or simply as a hobby. Targets of varmint hunting The term ''varmint'' is a US colloquial term for ''vermin'', th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
