The 450 Bushmaster cartridge has quickly gained popularity among hunters and enthusiasts seeking a powerful and versatile round. Its ability to deliver substantial stopping power at longer ranges makes it a compelling choice. However, the addition of subsonic ammunition and a suppressor opens up a whole new world of applications, making it an even more attractive option for various uses. This article delves into the specifics of the 450 Bushmaster subsonic suppressed setup, examining its benefits, drawbacks, and optimal applications.
Understanding the 450 Bushmaster Cartridge
The 450 Bushmaster, designed by Tim Leghorn, boasts a powerful performance significantly exceeding its .458 SOCOM predecessor. Its larger case capacity allows for heavier bullets and higher powder charges resulting in greater energy and range. The cartridge's relatively short length suits various AR-15 platform rifles, enhancing its adaptability. Key characteristics include:
- Caliber: .450 inches
- Case: Based on the .223 Remington case
- Bullet Weights: Typically ranges from 250 to 300 grains
- Velocity: Subsonic loads typically achieve velocities below 1100 feet per second (fps)
Comparison to Other Calibers:
| Caliber | Bullet Weight (gr) | Velocity (fps) | Energy (ft-lbs) | Recoil |
|---|---|---|---|---|
| 450 Bushmaster | 250 | 1050 (subsonic) | ~600 | High |
| 458 SOCOM | 300 | 1900 | ~1500 | Very High |
| 300 Blackout | 220 | 1050 (subsonic) | ~450 | Moderate |
(Note: Values are approximate and can vary depending on ammunition and barrel length.)
The Advantages of Subsonic 450 Bushmaster Suppressed
Using subsonic ammunition in conjunction with a suppressor dramatically reduces the sound signature of the 450 Bushmaster, offering several key benefits:
-
Reduced Noise: This is the primary advantage. Subsonic rounds, traveling slower than the speed of sound, generate less sonic boom. A suppressor further mitigates the remaining muzzle report, making it ideal for hunting in noise-sensitive environments, tactical situations, or simply practicing at home.
-
Improved Accuracy: The reduced recoil and muzzle blast associated with subsonic ammo and suppressors can contribute to improved accuracy, particularly for novice shooters.
-
Increased Concealment: Lower noise levels enhance concealment, especially in hunting or tactical scenarios.
-
Reduced Recoil: While the 450 Bushmaster has noticeable recoil, subsonic loads and suppressors further lessen this, improving shooter comfort and control, especially during extended shooting sessions.
Drawbacks and Considerations
While subsonic suppressed 450 Bushmaster offers many advantages, some drawbacks must be acknowledged:
-
Reduced Velocity and Energy: Subsonic rounds have inherently lower velocity and energy compared to supersonic counterparts. This means reduced range and potentially less stopping power, although still substantial for its intended purposes.
-
Limited Ammunition Availability: The availability of commercially loaded subsonic 450 Bushmaster ammunition is relatively less compared to more common calibers. This can impact pricing and availability.
-
Suppressor Cost and Maintenance: Suppressors represent a considerable investment, and regular maintenance and cleaning are crucial for optimal performance and longevity.
-
Potential for Increased Back Pressure: Running a suppressor with subsonic ammo may increase back pressure on the bolt and other firearm components. Choose high-quality components designed to handle this.
Optimal Applications
The subsonic suppressed 450 Bushmaster configuration excels in specific scenarios:
-
Close-to-Medium Range Hunting: Ideal for hunting hogs, deer, and other medium-sized game within a reasonable range, where noise reduction is prioritized.
-
Home Defense: While the powerful recoil should be considered, the reduced noise level makes it a discreet option for home protection, minimizing the impact of the gunshot.
-
Tactical Situations: In scenarios demanding sound reduction, the subsonic setup offers a quiet yet potent solution.
-
Night Hunting: The reduced report makes it better suited for night hunting where noise may spook prey or alert other hunters in the area.
Choosing the Right Suppressor and Ammunition
Selecting the correct suppressor and ammunition is paramount for optimal performance. Research and choose a high-quality suppressor designed for the 450 Bushmaster caliber. Pay close attention to the suppressor’s specifications regarding back pressure and gas flow. Ensure the ammunition is specifically designed for subsonic operation within the 450 Bushmaster. Experimentation may be necessary to find the ideal combination.
Conclusion
The 450 Bushmaster subsonic suppressed configuration is a powerful and versatile system offering numerous benefits for hunters and enthusiasts. While there are considerations regarding reduced velocity and ammunition availability, the enhanced noise reduction, improved accuracy, and increased concealment make it a compelling choice for specific applications. With careful selection of equipment and ammunition, the 450 Bushmaster subsonic suppressed can deliver superior performance and a quiet, effective shooting experience. Remember always to prioritize safety and adhere to local regulations when using firearms and suppressors.
