Quick Answer
A heavier bullet in .450 Bushmaster is used for big game because it provides sufficient kinetic energy to instantly drop larger animals, such as elk and moose, with a single shot. This is due to the cartridge's relatively low muzzle velocity, which requires a heavier bullet to achieve the necessary stopping power. The heavier bullet also helps to minimize over-penetration.
Ballistic Performance
The .450 Bushmaster is a straight-walled cartridge that operates at a relatively low muzzle velocity of around 2,000-2,200 feet per second (FPS). To compensate for this lower velocity, a heavier bullet is used to ensure that it delivers sufficient kinetic energy to the target. A 300-grain bullet, for example, will have a kinetic energy of around 3,000-3,200 foot-pounds (ft-lbs), which is sufficient to drop larger animals quickly. In contrast, a lighter bullet may not deliver enough energy to penetrate deep enough and still exit the animal, which can lead to over-penetration and damage to surrounding tissue.
Bullet Selection
When selecting a bullet for the .450 Bushmaster, it’s essential to choose one that is designed for deep penetration and expanded performance. This typically means selecting a bullet with a weight of 300-400 grains and a diameter of around 0.45 inches. The bullet should also have a suitable expansion ratio and a jacket that is designed to withstand the high velocities of the cartridge. For big game hunting, a bullet with a controlled expansion design, such as the Hornady InterLock or the Speer Grand Slam, is a good choice.
Hunting Techniques
When hunting with a .450 Bushmaster, it’s essential to use proper hunting techniques to ensure a clean and quick kill. This includes shooting from a stable position, using a good rest, and aiming for a vital area such as the heart or lungs. It’s also essential to follow safe hunting practices, including wearing protective gear and respecting the animal’s natural behavior. By combining a heavy bullet with proper hunting techniques, hunters can ensure a quick and humane kill, and minimize the risk of wounding the animal.
