The .460 S&W Magnum is a powerful cartridge, commanding respect from both hunters and competitive shooters. Its immense stopping power and flat trajectory make it a favorite for dangerous game hunting and long-range shooting. However, loading this potent round requires meticulous attention to detail and a deep understanding of reloading safety. This guide delves into the intricacies of 460 S&W load data, providing essential information for safe and effective reloading.
Understanding the .460 S&W Magnum
Before diving into load data, it's crucial to understand the cartridge itself. The .460 S&W Magnum is a large-bore, semi-rimmed cartridge designed for powerful performance. Its large case capacity allows for significant powder charges, resulting in high velocities and substantial recoil. This power necessitates robust firearms and careful reloading practices.
Key Characteristics of the .460 S&W Magnum:
- High Pressure: The .460 S&W operates at high pressures, making it critical to use the correct load data and follow safety protocols precisely. Improper loading can lead to catastrophic firearm failure.
- Heavy Recoil: The substantial recoil necessitates a firm grip and proper shooting technique to manage the firearm effectively.
- Versatile Applications: This round excels in hunting large game, and its accuracy makes it suitable for long-range shooting.
- Limited Availability: Some components, like specific bullets and brass, might be less readily available compared to more common calibers.
Essential Reloading Equipment for .460 S&W Magnum
Reloading the .460 S&W Magnum requires specific equipment capable of handling the high pressures involved. Cutting corners on equipment can result in dangerous situations.
- Reloading Press: A sturdy, robust press is essential. A single-stage press offers precision control, while progressive presses can increase loading speed. Choose a press specifically rated for magnum cartridges.
- Dies: A full set of dies is needed: sizing die, powder measure, seating die, and possibly a crimp die. Ensure the dies are specifically designed for the .460 S&W Magnum.
- Powder Measure: An accurate powder measure is critical for consistent loads. Scale verification is a must.
- Scale: A digital powder scale is recommended for precise powder measurement.
- Case Trimmer: Trimming cases to a uniform length is critical for consistent performance and safety.
- Bullet Puller: This tool is crucial for safely removing incorrectly loaded bullets.
Choosing the Right Components
Selecting the right components is paramount for safe and effective reloading. Using incorrect components can drastically impact performance and safety.
Bullets:
- Bullet Weight: Bullet weight ranges from 200 grains to over 400 grains. Choosing the right weight depends on the intended use (hunting, target shooting).
- Bullet Type: Several bullet types are available, including jacketed hollow points (JHP), jacketed soft points (JSP), and full metal jacket (FMJ). Consider the intended purpose when making your selection.
Powder:
Selecting the correct powder is critical for safety and optimal performance. Never substitute powders without consulting reliable load data from reputable sources. Popular choices include:
- Hodgdon H110: A very popular option for magnum handgun loads.
- Alliant 2400: Another strong contender often used in magnum calibers.
Primers:
Use large rifle magnum primers, specifically designed for the high pressures generated by the .460 S&W Magnum.
Brass:
Use new or once-fired brass in good condition. Damaged brass can lead to inconsistent loads and potential safety hazards.
