The .460 S&W Magnum is a powerful cartridge, demanding respect and careful attention to detail when reloading. This guide provides comprehensive Hornady load data for the .460 S&W, emphasizing safety and accuracy. Always prioritize safety and consult your reloading manual before attempting any reloading. This information is for guidance only and does not replace the need for a comprehensive reloading manual.
Understanding Hornady's Approach to .460 S&W Load Data
Hornady, a reputable ammunition manufacturer, provides load data based on extensive testing and adheres to industry safety standards. Their data emphasizes the use of high-quality components to ensure consistent and reliable performance. Understanding the nuances of their data is crucial for safe and accurate reloading. Hornady's data typically specifies powder type, powder charge weight, bullet weight, overall cartridge length (OAL), and expected velocity. It often includes warnings about pressure signs and maximum loads, which should never be exceeded.
Key Considerations When Using Hornady .460 S&W Load Data
- Powder Selection: Hornady specifies particular powders for optimal performance and safety. Using a different powder without consulting a reliable reloading manual is extremely dangerous. Powder characteristics, burn rates, and their interaction with different bullet weights are critical factors that influence pressure.
- Bullet Selection: Bullet weight significantly impacts pressure. Using a heavier or lighter bullet than specified will affect the pressure within the cartridge case. Always stick to the recommended bullet weight.
- Case Preparation: Consistent case preparation is critical. Cases should be properly cleaned, sized, trimmed, and primed. Inconsistencies can lead to unsafe pressure spikes.
- OAL Measurement: The Overall Cartridge Length (OAL) is crucial. An OAL that's too long can cause excessive pressure, while one that's too short can lead to inconsistent ignition and accuracy problems. Use a case gauge to ensure your loaded rounds meet the specifications.
- Pressure Signs: Understand the signs of excessive pressure. These include flattened primers, excessive case head expansion, and unusual noise or recoil. If you observe any of these, immediately cease reloading and investigate the cause.
