.300 Winchester Magnum – Wikipedia, La Enciclopedia Free

He .300 Winchester Magnum (abbreviated . 300 win mag ), from 7,62 x 67 In the metric system, it is a metallic cartridge of central fire, of a cappellaged caps and without rings, designed to be used in bolt rifles, conceived for the purposes of big game, and introduced by Winchester Repeating Arms Company in 1963.

He was the last of the Winchester Magnum calibres family to be launched to the market, in 1963, and preceded by the .264 Winchester Magnum, the .458 Winchester Magnum and the .338 Winchester Magnum, which were introduced to the market at the end of the decade of the 1950s.

The .300 Winchester Magnum was also Winchester’s response to 7mm Remington Magnum, developed by Remington that was launched to the market in 1962, which had eclipsed the sales of the recent then .264 Winchester Magnum. ^{[ first ]} ​ ^{[ 2 ]} ​ ^{[ 3 ]} ​

Like the other BELTED MAGTUM cartridges, the design of the .300 Win Mag, is based on the .300 Holland & Holland Magnum, which, in turn, developed adjusting the neck of the caps of the .375 Holland & Holland Magnum, To house a .308 caliber projectile. However, for the design of .300 Win Mag, the length of the cap was also reduced so that it can be fed from a standard size bolt mechanism similar to that used in cartridges such as .270 Winchester or the .30-06 Springifeld , of the winchester bolt rifle model 70.

Another characteristic of the .300 Win Mag design is the increase in the load capacity of the cap without increasing its length, by increasing the shoulder height at the costs of a slight reduction in the length of the neck of the cap, characteristic which allows it to generate an output speed, with a 150 -grain projectile, between 3,200 and 3,300 feet per second of the canyon’s mouth, and approximately 180 grain projectiles, an exit speed of approximately 3,000 feet per second, returning Al .300 Win Mag A direct competitor of .7mm remits and an alternative to 300 Weatherby Magnum that can be operated a shorter, economical mechanism and in a lighter rifle. ^{[ 4 ]} ​

Before the .300 Win Mag was designed, there were others. “300 Magnum”. In 1913, the .30 Newton had been developed after the launch of the .300 H & H Magnum, in 1925, also known as the Super 30 but that was too long to be used in a Mauser or Springfield mechanism in standard length.

In 1943, Roy Weatherby created a line of proprietary cartridges, starting with .270 Weatherby Magnum, developed from the H&H Magnum cap, reduced to be used in a standard length mechanism, and to which the angle of the shoulders was pronounced . The .300 Weatherby Magnum was introduced the following year, but the length of the cap was not reduced to make the most of the gunpowder load, and thus had to be used from a long magnum length mechanism.

In 1958, Winchester emulated the development of the first Weatherby caps, introducing three Belted Magnum cartridges; The .264 Winchester Magnum, the .338 Winchester Magnum and the .458 Winchester Magnum. All starting from the .375 Holland & Holland Magnum caps, reduced to be fed from a standard length mechanism. But the lack of a .300 Magnum that can be used from a standard mechanism did not go unnoticed, promoting the appearance of cartridges such as .30-388 Winchester and the .308 Magnum standard, developed by the normal ammunition factory, which by then It produced the Weatherby cartridges.

The .300 Win Mag was finally introduced by Winchester to be used in model 70. The new cartridge was the result of adjusting the .338 Winchester Magum neck to host a .30 caliber projectile, and to which the distance between the base and shoulder in 4 millimeters, and it was given a length of 3 millimeters, causing the cartridge to have a neck shorter than the diameter of the projectile.

Although the popularity of .300 Winchester Magnum was not instantaneous, partly because of the appearance of .7mm Remington Magnum the previous year and because the following year of its introduction the version of the Winchester Model 70 was discontinued that had a controlled feed bolt . With the passage of time it managed to become the most popular of the Magnum metal cartridges to date. ^{[ 5 ]} ​

The high availability of .300 Win Mag and its availability in popular rifles such as the Winchester Model 70, Remington 700 or the Ruger M77, have conferred the .300 Win Mag the popularity it has until today. Although the .300 H & H MAG, .30-338 Winchester Magnum and the .308 Magnum Standard appeared before, these three cartridges have become practically obsolete, while the .300 Win Mag has constantly gain popularity.

Performance [ To edit ]

The .300 Win Mag is a cartridge that was basically developed for the purpose of older hunting. It is able to reduce any kind of fauna in the world, only offering a marginal performance to reduce dangerous animals of coarse skin such as the elephant, buffalo of the end or the rhinoceros. But the .300 Win Mag stands out mainly for the hunting of goats and deer of all size where very variable shooting distances can be presented.

While it was clearly created as a major hunting cartridge, the .300 Win Mag also became popular in long -distance shooting competitions, in addition to being adopted by elite shooters in police forces and snipers of the United States Army.

150 grains [ To edit ]

With a 150 -grain projectile (ballistic coefficient: .435), and an output speed, which, with some loads it can reach 3,400 feet per second, the maximum flat trajectory will reach 367 yards, having impacted three inches above from white to 100 yards. ^{[ 6 ]} The high speed conferred by a flat trajectory is extremely effective for the hunting of lighter hunting species at considerable distances.

165 – 168 grains [ To edit ]

The 168 -grain projectiles confer to the .300 Win Mag an output speed of approximately 3,200 feet per second, which translate into a flat trajectory in addition to a projectile with a greater ballistic coecetive that allows more efficient cross winds to be overcome. It is an ideal weight for hunting medium -sized species in mountain areas.

180 – 185 grains [ To edit ]

However; With weights from 180 grains is that the .300 Winchester Magnum achieves its best benefits according to many hunters and shooters, with average initial speeds of 2,950 feet per second, a little lower than those that it achieves with more light projectiles, but with a High ballistic coefficient, which allows you The projectile can overcome the wind efficiently and thus keep its energy for long distances.

190 – 220 grains [ To edit ]

The cartridges loaded with peso projectiles between .190 and 220 grains have become one of the most popular options for long -range shooting competitions. ^{[ 7 ]} ​ ^{[ first ]} ​

The .300 Winchester Magnum produces a great setback, greater than the .30-06 Springfield. However, Remington and Hornady have made available cartridges with a decline called “Managed-Recoil”, which have a lower setback and performance similar to .30-06. ^{[ 8 ]} ​

The maximum effective range is generally 1,110 meters (1,210 yards), using bullets with little drag force. The impacts with an accuracy of less than a minute of arc at 910 meters (1000 yards) are not rare using competition ammunition in rifles built on request. The speed of a 180 -grain bullet (11.7 grams) with maximum gunpowder load from a 61 cm (24 -inch) cannon is 907 ± 7.6 m/s (2975 ± 25 feet/second). ^{[ 9 ]} ​ ^{[ 8 ]} ​

The 300 Winchester Magnum caliber rifles, usually have a cannon for a turn or passage of 1:10, which allows them to stabilize peso projectiles between 150 and 220 grains, making it extremely versatile for all types of hunting species Greater, with very few exceptions. ^{[ ten ]} ​

With 150 -grain commercial ammunition, 300 Win Mag reaches an initial speed of 3,250 feet per second of the mouth of a 24 -inch cannon, achieving a very flat path to hunt medium -sized animals such as white -tailed deer, mule deer, rams , goats and roe deal at considerable distances emphatically.

Loaded with 165 or 168 -grain projectiles, the .300 Winchester Magnum also offers a very flat trajectory and a greater ballistic coefficient, which allows it to overcome crossed winds without being diverted, making it an interesting option for hunting long distances in mountain areas . ^{[ first ]} Due to the wide spectrum of pesos of projectiles and types of .30 caliber bullets that exist, the 300 Win Mag is effectively used for the hunting of a wide variety of species of hunting interest and in different geographical conditions.

Probably the most popular weight used by hunters with the .300 Win Mag, is the 180 -grain projectile, giving it a perfect balance between energy, trajectory and high ballistic coefficient, and the most appropriate option for hunting more weight species such as wapitis and alces. With a 180 -grain projectile, the 300 Win Mag borders 3,000 feet per second and with some recharges can approach 3,200 feet, achieving a performance similar to that of the .300 Weatherby Magnum. ^{[ 5 ]} ​

Due to the versatility of the cartridge, the .300 Winchester Magnum is an option for those who prefer a single weapon for hunting of different major hunting species, since choosing the adequate weight and construction projectile can effectively reduce any prey in the five continents, limiting only to dangerous animals of coarse skin such as, for example, the elephant, buffalo or rhino. It is for this reason that ammunition .300 Winchester Magnum is relatively easy to find in any country in the world where the big hunt is practiced. Being also an option for the practice of sports shooting, has also contributed its popularity worldwide, to the point of being the most popular “magnum” cartridge in the world.

Popularity [ To edit ]

Like other cartridges of the Winchester Magnum family, the popularity of the .300 is based largely because it is based on the Holland & Holland cap but shortened, shortened ^{[ 11 ]} That of a maximum cartridge length of 3.34 inches, allowing it to be used in rifles with a medium or standard length bolt mechanisms, such as the Winchester Model 70, the Remington 700 or the Ruger M77, designed to feed cartridges of the average length of 30-06 Springfield or the .270 Winchester; And that keeps it as the most popular. 378 Weatherby Magnum, .30 Nosler, .300 Remington Ultra Magnum. ^{[ 8 ]} ​ ^{[ twelfth ]} ​

The benefits of the 300 Winchester Magnum virtually replicate to the .308 Magnum standard, also developed based on 300 h & h mag 168 grains), although in ammunition with pesos projectiles from 180 grains, the 300 Win Mag is slightly higher. Although the 300 wsm can be fed from a short action mechanism, of the same length as the .308 Winchester or 6.5 Creedmoor, the feeding of the 300 Win Mag is more reliable and soft. ^{[ 13 ]} ​ ^{[ 14 ]} ​

One of the criticisms that are made at 300 Win Mag is the design of the cap, which has a relatively short neck, which was developed in this way by Winchester with the aim of loading the greatest amount of gunpowder, but which according to some experts could affect precision, something that has never been proven in practice.

While it is a popular choice cartridge to hunt large ungulates such as Wapiti or Kudú for generating greater energy than conventional 7.62 mm caliber cartridges, the .300 Win Mag, is commonly used to hunt all types of cervids, Like the white tail deer, the mule deer and goats of all weight around the world. ^{[ 15 ]} ​

Currently the .300 Winchester Magnum is the most popular “magnum” caliber, even exceeding 7mm Rem Mag sales.
