Description
The HSM Bear Load .450 Bushmaster is purpose-built ammunition for those who hunt where terminal performance matters most. This load pairs a heavy 300-grain jacketed soft point bullet with temperature-stable powders and quality brass cases, giving you the kind of hitting power the .450 Bushmaster is known for. You're looking at 1950 feet per second and roughly 2,500 foot-pounds of muzzle energy, which translates to effective hunting performance on deer, hogs, and black bear within practical shooting distances.
Heavy-hitting HSM Bear Load Design
HSM has been making the Bear Load line since 2011, and this .450 Bushmaster loading reflects that experience. The 300-grain bullet weight puts this at the heavier end of common factory .450 loads, trading some velocity for maximum momentum and penetration. This becomes important when you're dealing with thick hide, heavy bone structure, and the need for one-shot stops. The jacketed soft point bullet expands reliably on impact while maintaining the structural integrity you need for deeper penetration than lighter alternatives.
Reloadable Brass and Field-Ready Packaging
Each round comes in reloadable boxer-primed brass cases, which means if you handload, you've got brass worth saving. The 20-round box packaging is what you want for field use and hunting trips, not range sessions. The straightforward, no-nonsense setup reflects that this ammunition was built for working hunters who understand that reliability matters more than fluff.
Right for the Job
The .450 Bushmaster itself has earned a solid reputation among hunters in straight-wall-only states and those who appreciate the cartridge's moderate recoil relative to its terminal performance. This load sits in that sweet spot where you get heavier-for-caliber bullet weight without sacrificing reasonable velocities. It'll handle brush country hunting just fine and performs particularly well inside 200 yards where the majority of hunting actually happens.

Frequently Asked Questions
What game is this HSM Bear Load suitable for?
The 300-grain JSP loading works well for deer, hogs, and black bear hunting within reasonable distances, typically under 200 yards. The heavy bullet weight and solid construction provide the penetration needed for larger game. It's particularly effective in brush and timber where longer shots aren't realistic.
Is this ammunition reloadable?
Yes, the cases are reloadable brass with boxer primers, making them suitable for handloaders. This can help offset long-term shooting costs if you reload your own ammunition.
How does the 300-grain loading compare to lighter .450 Bushmaster loads?
The 300-grain bullet is heavier than typical factory loads and travels at a lower velocity, around 1950 fps compared to 2200+ fps for lighter bullets. This trade-off gives you more momentum and deeper penetration, which is valuable for hunting larger or tougher game, though trajectory drops off faster downrange.
What's the muzzle energy on this load?
This ammunition generates approximately 2,532 foot-pounds of energy at the muzzle, which is substantial and well-suited to the hunting applications it's designed for. That energy level supports clean, effective performance on big game at hunting distances.
