BUY Federal Premium BARNES TSX .300 Winchester Magnum 165Grain
Federal Premium BARNES TSX .300 Winchester Magnum 165Grain is extremely versatile and has been adopted by a wide range of users including hunters, target shooters, military units, and law enforcement departments. Hunters found the cartridge to be an effective all-around choice with bullet options ranging from the flatter shooting 165 grain to the harder hitting 200+ grain selections available from the factory. The .300 Win Mag remains the most popular .30 caliber magnum with American hunters, despite being surpassed in performance by the more powerful .300 and .30-378 Weatherby Magnums and the newer .300 Remington Ultra Magnum. It is a popular selection for hunting moose, elk, and bighorn sheep as it can deliver better long range performance with better bullet weight than most other .30 caliber cartridges. Military and law enforcement departments adopted the cartridge for long range sniping and marksmanship. As a testament to its accuracy, since its introduction it has gone on to win several 1,000-yard (910 m) competitions.
Prior to the design of the .300 Winchester Magnum there were several cartridges that provided what could be best described as a magnum level of energy. The heritage of .30 caliber (7.62 mm) magnums can be traced back to the .30 Newton in 1913 and to the .300 H&H Magnum in 1925. The .300 H&H Magnum was too long for the Mauser and Springfield standard length rifle actions and required specialized rifles with a Magnum size action.
Beginning with the .270 Weatherby Magnum in 1943, Roy Weatherby introduced a line of cartridges that while based on the Magnum H&H case were shortened to fit a standard length (2.5 in [63.50 mm]) action. The Weatherby cartridges involved blowing out (reducing the taper) of the Magnum H&H cases, bottlenecking them to the required caliber and shortening them to fit the standard rifle actions of the era. The .300 Weatherby Magnum was introduced in several grains.
Federal Premium BARNES TSX .300 Winchester Magnum 165Grain was introduced by Winchester for use in the Model 70 rifle. The introduction of the .300 Winchester Magnum was not unforeseen; rather, its introduction was anticlimactic. Winchester developed the .300 Winchester Magnum by taking the .338 Winchester Magnum, which was introduced in 1958, and moved the shoulder forward by 4.0 millimetres and lengthening it by 3.0 millimetres (0.120 in). This caused the cartridge to have a neck shorter than the diameter of the bullet. There has been some speculation that if the cartridge was released earlier, the dimensions of the cartridge would have matched the .30-338 Winchester wildcat cartridge. Since its introduction the cartridge has remained extremely popular.
