What differences in performance should I expect with various .450?

Bullet Selection and Velocity

When selecting a .450 Bushmaster load, bullet weight and diameter play a crucial role. Heavier bullets, like the 250-grain option, deliver a significant amount of kinetic energy, making them suitable for larger game like elk and moose. However, this comes at the cost of velocity, with most 250-grain loads topping out around 2,000-2,100 feet per second. In contrast, lighter bullets like the 175-grain option can reach velocities of up to 2,400 feet per second, making them better suited for smaller game like deer.

Load Combinations and Their Effects

The choice of load combination also affects the .450 Bushmaster’s performance. For example, using a lighter bullet and a slower burning powder like H4831 can produce a flatter shooting trajectory, while a heavier bullet and a faster burning powder like H1000 can deliver more kinetic energy. As a general rule, a 250-grain bullet with H4831 will produce a more manageable recoil, while a 250-grain bullet with H1000 will offer more stopping power. When choosing a load combination, it’s essential to consider the specific requirements of your rifle and the game you’re hunting.

Real-World Examples and Comparison

For a real-world example, consider the difference between the Hornady 250-grain SST load and the Barnes 250-grain TSX load. The Hornady load, with a velocity of 2,040 feet per second, delivers 1,800 pounds of kinetic energy, while the Barnes load, with a velocity of 2,000 feet per second, delivers 1,900 pounds of kinetic energy. This difference in kinetic energy can be significant when hunting larger game, and choosing the right load combination is essential to achieving optimal performance.
