The .460 Smith & Wesson Magnum is a potent cartridge, demanding careful consideration when it comes to reloading. This guide delves into Hornady load data for the .460 S&W, emphasizing safety and accuracy. Understanding and meticulously following load data is crucial for safe and effective shooting. Ignoring manufacturer recommendations can lead to dangerous pressure spikes and potential firearm damage. This article provides information, but always consult your specific Hornady manual and other reliable sources before attempting to reload any ammunition.
Understanding Hornady's Approach to .460 S&W Load Data
Hornady, a respected name in ammunition and reloading components, provides detailed load data in their manuals. These manuals are meticulously compiled through extensive testing to ensure safety and performance. Their data considers various factors, including bullet weight, powder type, and case capacity, offering a range of loads suitable for different applications – from hunting to target shooting. Never deviate from their specified data unless you have extensive reloading experience and the necessary equipment for precise pressure testing.
Key Factors Affecting .460 S&W Loads:
- Bullet Weight: Heavier bullets generally require more powder to achieve optimal velocity. Hornady's data will clearly outline the powder charge for each bullet weight they recommend.
- Powder Type: The type of powder significantly impacts pressure and velocity. Hornady specifies the precise powder type and its suitability for the .460 S&W cartridge. Using an incorrect powder can be dangerous.
- Case Capacity: Slight variations in case capacity can affect pressure. Using consistently sized cases is essential for consistent results and safety.
- Primer Type: Hornady will recommend a specific primer type for their load data. Using a different primer may affect ignition and pressure.
- Barrel Length: Barrel length influences velocity. Hornady's data often specifies a standard barrel length, so be aware that shorter or longer barrels may impact performance.
Deciphering Hornady's .460 S&W Load Data Charts
Hornady's load data charts typically follow a standardized format, typically including:
- Bullet Weight (grains): This clearly indicates the weight of the bullet being used.
- Bullet Type: Details the bullet's construction (e.g., jacketed hollow point, full metal jacket, etc.). This affects ballistic performance.
- Powder Type: Specifies the brand and type of powder recommended.
- Powder Charge (grains): This is the critical data indicating the weight of the powder to use. This must be followed precisely.
- Primer Type: The specific primer recommended by Hornady for the load.
- Velocity (fps): The expected muzzle velocity at a specified barrel length.
- Pressure (PSI): The maximum pressure generated by the load. Staying within safe pressure limits is paramount.
Example Load Data (Hypothetical - Always Refer to the Official Hornady Manual):
| Bullet Weight (grains) | Bullet Type | Powder Type | Powder Charge (grains) | Primer Type | Velocity (fps) | Pressure (PSI) |
|---|---|---|---|---|---|---|
| 300 | Jacketed Hollow Point | Hornady XMP574 | 70 | CCI 200 | 2000 | 55,000 |
| 350 | Jacketed Soft Point | Hornady XMP574 | 75 | CCI 200 | 1900 | 52,000 |
Note: This is a hypothetical example and should not be used for reloading. Always consult the official Hornady reloading manual for accurate and up-to-date data.
Safety Precautions When Reloading .460 S&W
Reloading the .460 S&W requires meticulous attention to safety. Here are essential precautions:
- Always wear safety glasses and hearing protection.
- Work in a well-ventilated area.
- Use a single-stage or progressive reloading press appropriate for the cartridge.
- Use a powder scale to accurately measure powder charges.
- Double-check all measurements before seating primers and bullets.
- Never exceed the maximum listed pressure in the Hornady load data.
- Inspect each round carefully for defects before loading it into the firearm.
- Start with lower end charges listed in the load data and work your way up gradually, closely monitoring pressure signs.
- Regularly maintain your reloading equipment.
- Keep your loading area organized and free from distractions.
Conclusion
Reloading the .460 S&W Magnum is a rewarding but inherently dangerous undertaking. This guide provides a foundation for understanding Hornady's load data and the critical safety measures involved. Always prioritize safety and consult the official Hornady reloading manual before beginning. Remember that this information is for educational purposes only. Incorrect reloading practices can result in serious injury or death. The responsibility for safe reloading rests solely with the reloader.
