In this article, we’ll delve into the features of the .450 Bushmaster, its suitability for hunting, and how you can build your own AR-15 rifle with a .450 Bushmaster Upper.
Hunt With Your AR-15 Using a .450 Bushmaster Upper
The .450 Bushmaster has gained popularity due to its reputation as one of the finest hunting cartridges, particularly for mid-range big-game hunting.
While not designed for long-range shooting, this cartridge excels as a brush gun for taking down elk, deer, and bear.
History of the .450 Bushmaster
The credit for designing the .450 Bushmaster cartridge goes to Colonel Jeff Cooper.
As a seasoned US Marine with combat experience in WWII and the Korean War, Cooper was dissatisfied with the performance of .223 Remington/5.56x45mm NATO cartridges and sought something better.
Inspired by the concept of utilizing an AR-15 platform, Cooper envisioned a cartridge similar to the .45 ACP pistol cartridge but with increased size, accuracy, and armor-piercing capabilities.
LeMag Firearms explored Cooper’s idea, but it was Bushmaster who secured the license.
Hornady, commissioned by Bushmaster, developed the .45 Professional for this concept. However, Hornady’s innovation led to further improvements, such as shortening the length to accommodate flex-tip bullets, resulting in the birth of the .450 Bushmaster.
