The .458 Lott is a powerful and versatile cartridge, popular among hunters and enthusiasts for its impressive stopping power. However, loading for this round requires precision and a thorough understanding of safety protocols. This comprehensive guide delves into the specifics of 458 Lott load data, providing crucial information for safe and effective reloading. Remember, always consult your reloading manual and prioritize safety above all else. Incorrect load data can lead to dangerous consequences.
Understanding the .458 Lott Cartridge
The .458 Lott, a wildcat cartridge based on the .458 Winchester Magnum case, is known for its substantial bullet diameter (.458 inch) and impressive energy levels. This makes it suitable for large game hunting, from dangerous African animals to North American big game. Its popularity stems from its ability to deliver consistent accuracy and devastating power at longer ranges compared to some other large-bore cartridges.
Key Features of the .458 Lott:
- High-Velocity Potential: Achieves significantly higher velocities than its parent cartridge, the .458 Winchester Magnum.
- Versatility: Suitable for a wide range of bullet weights and designs.
- Powerful Stopping Power: Provides exceptional knock-down power for large game hunting.
- Relatively High Recoil: Requires robust rifles and proper shooting techniques.
- Case Capacity: Larger case capacity allows for higher powder charges, enhancing velocity and energy.
458 Lott Load Data: A Detailed Look
The following data is for informational purposes only. Always consult your reloading manual and adhere to its recommended load data before attempting any reloading. This data is based on commonly used powders and bullet weights, but variations exist across different manufacturers and specific firearms.
Powder Selection:
Choosing the right powder is crucial for optimal performance and safety. Popular choices for .458 Lott loads include:
- IMR 7828SSC: A popular choice known for its consistent burn rate and suitability for heavier bullets.
- Hodgdon H1000: Another excellent choice for heavy bullets, providing high velocity and good accuracy.
- Reloder 26: Offers excellent accuracy and consistent performance across a range of bullet weights.
| Powder Type | Bullet Weight (grains) | Powder Charge (grains) | COL (inches) | Primer | Notes |
|---|---|---|---|---|---|
| IMR 7828SSC | 500 | 90 | 3.625 | Large Rifle Magnum | Start Low, Work Up - Test loads carefully |
| IMR 7828SSC | 400 | 85 | 3.600 | Large Rifle Magnum | Start Low, Work Up - Test loads carefully |
| Hodgdon H1000 | 500 | 95 | 3.625 | Large Rifle Magnum | Start Low, Work Up - Test loads carefully |
| Hodgdon H1000 | 400 | 90 | 3.600 | Large Rifle Magnum | Start Low, Work Up - Test loads carefully |
| Reloder 26 | 500 | 92 | 3.625 | Large Rifle Magnum | Start Low, Work Up - Test loads carefully |
| Reloder 26 | 400 | 88 | 3.600 | Large Rifle Magnum | Start Low, Work Up - Test loads carefully |
COL (Cartridge Overall Length): This refers to the total length of the loaded cartridge. It's crucial to maintain the correct COL to ensure proper feeding and function in your rifle. Incorrect COL can lead to malfunctions and potential damage to your firearm.
Primer: Use Large Rifle Magnum primers.
Bullet Selection:
Bullet selection significantly impacts the performance of your 458 Lott loads. Consider factors like bullet weight, construction, and intended use when making your choice.
- Heavier Bullets (500 grains and above): Ideal for long-range shooting and larger game.
- Lighter Bullets (350-400 grains): Suitable for closer-range hunting and potentially for practice.
- Solid Copper Bullets: Excellent for penetration and minimal expansion for dangerous game hunting.
- Lead Core Bullets: More affordable options, but require careful consideration of bullet design for expansion and performance.
Note: Always choose bullets specifically designed and rated for the velocities your load data produces.
Safety Precautions:
Reloading is an inherently dangerous process. Failure to adhere to strict safety guidelines can lead to serious injury or death.
- Consult your reloading manual: This is the most critical step. Follow the manual's instructions precisely.
- Start low, work up: Never start at the maximum load. Begin with the minimum charge, and increase incrementally, carefully observing pressure signs.
- Use a chronograph: A chronograph is essential for verifying velocity, ensuring consistent performance across your loads.
- Inspect your cases: Discard any cases showing signs of damage or wear.
- Always wear safety glasses: Eye protection is critical to prevent injuries from projectiles or powder burns.
- Proper ventilation: Ensure adequate ventilation in your reloading area to prevent buildup of harmful gases.
Conclusion:
Reloading for the .458 Lott can be rewarding for experienced reloaders. However, it's crucial to prioritize safety and meticulously follow the recommendations from your reloading manual and trusted sources. By carefully selecting your components and adhering to precise loading procedures, you can create powerful and accurate loads for your .458 Lott rifle. Remember, accuracy and safety are paramount in reloading. Never compromise on either.
