The .500 S&W Magnum is a powerful cartridge, commanding respect for its immense stopping power and recoil. Reloading this round allows for precise customization of your ammunition, tailoring it to your specific firearm and intended use. However, safety is paramount when working with such potent rounds. This guide provides comprehensive information on .500 S&W Magnum load data, emphasizing safety and accuracy. Remember, always consult your firearm's manual before attempting to reload any ammunition.
Understanding the .500 S&W Magnum
The .500 S&W Magnum's popularity stems from its impressive ballistic performance. Its large diameter (.500 inches) and substantial case capacity deliver impressive energy and velocity. This makes it a formidable choice for hunting large game and self-defense situations, but also necessitates meticulous reloading practices.
Key Considerations for Reloading .500 S&W Magnum
- Case Preparation: Proper case preparation is crucial. This involves cleaning, resizing, and trimming cases to consistent lengths. Improperly prepared cases can lead to dangerous pressure spikes.
- Powder Selection: Choose powders specifically designed for magnum cartridges. Powders like Hodgdon's H110, Alliant 2400, and IMR 4227 are commonly used, but always cross-reference with published data.
- Bullet Selection: A wide variety of bullets are available, ranging from jacketed hollow points to solid cast lead bullets. Bullet weight and type significantly impact pressure and accuracy.
- Primer Selection: Magnum primers are essential for reliable ignition with the high pressures generated by the .500 S&W Magnum.
- Safety Precautions: Always wear safety glasses and hearing protection when reloading. Ensure your reloading press is securely mounted and that your workspace is clean and organized. Never exceed the maximum recommended pressure listed in load data.

Disclaimer: This table is a simplified representation. Many factors such as powder brand, lot variation, and environmental conditions can affect pressure. Always refer to multiple verified sources of reloading data specific to your components.
Troubleshooting Common Issues
- High Pressure Signs: Excessive pressure signs include flattened primers, excessive case head expansion, and unusual ejection patterns. If you observe any of these, immediately cease loading and investigate the cause.
- Accuracy Problems: Inaccuracy can stem from several sources, including improper bullet seating, inconsistent powder charges, or a dirty barrel. Address each potential issue systematically.
- Squibs: A squib load is when a cartridge fails to fully propel the bullet down the barrel. This can be extremely dangerous, leading to barrel damage or injury. Always inspect your cases and ensure they are properly loaded.
Beyond the Data: Safety First
The .500 S&W Magnum's immense power demands respect. Reloading it requires meticulous attention to detail and a thorough understanding of safe practices. Investing in high-quality reloading equipment, adhering to reliable data, and prioritizing safety are essential for avoiding dangerous situations. This guide offers helpful information, but should never replace proper training and consultation with experienced reloaders. Always start with minimum loads and work your way up cautiously. Never exceed the maximum recommended loads found in reputable sources. Consult a qualified reloading instructor if you are unsure about any aspect of this process. Your safety is paramount.
