Choosing the right cartridge for self-defense or competition shooting requires careful consideration of various factors. Two powerful contenders often top the list: the .45 Super and the .460 Rowland. While both boast impressive stopping power, they differ significantly in several key aspects. This in-depth comparison will help you understand the nuances of each cartridge and determine which best suits your needs.
Ballistics: Power and Performance
The core difference lies in their ballistic performance. The .460 Rowland, developed by renowned firearms designer, John Rowland, packs a significantly more powerful punch than the .45 Super. This translates to higher muzzle velocities and greater energy transfer upon impact, making it exceptionally effective for self-defense situations.
Muzzle Velocity and Energy:
- .460 Rowland: Typically boasts muzzle velocities exceeding 1500 fps (feet per second) and energy levels often surpassing 1000 ft-lbs (foot-pounds). The exact figures vary depending on the specific load and barrel length.
- .45 Super: While still potent, its muzzle velocity generally falls in the 1200-1400 fps range, with energy levels typically below 800 ft-lbs.
Recoil:
The increased power of the .460 Rowland comes at a cost – significant recoil. This can be challenging for shooters unfamiliar with powerful cartridges, potentially leading to reduced accuracy and faster fatigue. The .45 Super, while still possessing substantial recoil, is noticeably more manageable.
Ammunition Availability and Cost
Ammunition availability plays a crucial role in the practicality of any cartridge. While both .45 Super and .460 Rowland ammo are commercially available, the .45 Super generally enjoys wider distribution and a more readily available selection of bullet weights and types. The .460 Rowland, being a niche cartridge, may be harder to find in some areas and may command a higher price.
Gun Compatibility
A major factor to consider is the pistol's compatibility. The .460 Rowland requires specially designed pistols and often requires a conversion kit for standard 1911 platforms. This limits your gun choices compared to the .45 Super, which can be fired in many standard .45 ACP 1911 pistols with a simple barrel and magazine swap (though always verify compatibility with your specific firearm). This flexibility adds convenience and reduces the initial investment.
Practical Applications
The choice between the two heavily depends on your intended application:
Self-Defense:
Both cartridges are highly effective for self-defense. The .460 Rowland's superior power offers a clear advantage in stopping power, potentially resulting in faster incapacitation. However, its intense recoil may hinder accuracy under stress. The .45 Super offers a more manageable recoil profile while still delivering substantial stopping power.
Competition Shooting:
For competition shooting, the .45 Super often presents a better option. Its lower recoil allows for faster follow-up shots and improved accuracy, crucial for high-speed shooting events.
Conclusion: Choosing the Right Cartridge
Ultimately, the "better" cartridge depends entirely on your priorities and shooting experience. The .460 Rowland provides superior stopping power but demands a higher degree of shooter proficiency due to the intense recoil and potentially limited ammo availability. The .45 Super offers a more manageable recoil profile, wider ammunition selection, and greater compatibility with existing firearms, making it a versatile and practical option for many shooters. Carefully weigh the factors discussed above before making your decision. Consulting with experienced shooters and conducting thorough research will ensure you choose the cartridge that best suits your individual needs and capabilities.
