300 Winchester Mag Rifle Brass
The 300 Winchester Mag Rifle Brass also known as the .300 Win Magnum. This caliber is a popular North American cartridge. First of all, it is designed with a belted and bottlenecked case. The 300Win Mag rifle brass is based off the .375 H&H Magnum. That parent case has been blown out, shortened, and necked down to accept a .30 caliber bullet. It was first introduced by Winchester Repeating Arms Company in 1963 as a member of the family. The .300 Winchester Magnum fits in a standard length action. As a result, the .300 Winchester Mag is used throughout many shooting disciplines.
The cartridge is popular among hunters, target shooters, military units, and law enforcement departments. Hunters find that the cartridge has an all around hunting use. To this day, the Win Mag remains the most popular .30 caliber magnum cartridge with American hunters. So it is a popular selection for hunting larger game such as the elk, moose, and bighorn sheep. Most of all it delivers great long distance performance. This is achieved with better bullet weights than most other .30 caliber cartridges. In additions, the military and local law enforcement departments use the cartridge for long range sniping and marksmanship. Due to its accuracy, the .300 Winchester Magnum has won several 1,000-yard competitions. As a result, some shooters use it in Precision Rifle Matches.
