The .350 Legend cartridge has quickly gained popularity among hunters and shooters for its versatility and effectiveness on medium-sized game. One powder that's frequently paired with the .350 Legend is Hodgdon H110, known for its performance in magnum handgun cartridges. However, using H110 in the .350 Legend requires careful attention to detail and adherence to published load data. This guide provides a comprehensive overview of loading .350 Legend ammunition with H110, focusing on safety and accuracy.
Understanding the .350 Legend Cartridge
The .350 Legend, developed by Winchester, features a straight-walled design, making it suitable for use in AR-15 platform rifles. Its relatively low recoil and manageable velocity make it a good choice for both novice and experienced shooters. The cartridge's versatility stems from its ability to handle both lighter and heavier bullets, allowing for adjustments to its ballistic characteristics based on specific hunting situations or target practice. Understanding the cartridge's limitations and capabilities is crucial before experimenting with different powders.
Why Choose H110 for .350 Legend Loads?
Hodgdon H110 is a slow-burning, powerful powder often used in magnum handgun calibers. While not traditionally used in rifle cartridges, its performance in the .350 Legend, when loaded correctly, can be exceptional. H110's slow burn rate contributes to higher velocities and flatter trajectories than some faster-burning powders. However, its sensitivity to variations in charge weight necessitates meticulous attention to detail and adherence to manufacturer’s load data. Using H110 incorrectly can lead to dangerous over-pressure situations.
Crucial Safety Precautions:
- Always consult the latest Hodgdon reloading manual. Never rely on online forums or anecdotal evidence for load data.
- Start at the minimum charge weight listed in the manual. Gradually increase the charge weight in small increments, carefully monitoring pressure signs.
- Weigh your powder charges using a precision powder scale. Even minor variations in powder charge weight can significantly impact pressure. Do not use a volumetric measure.
- Carefully inspect your cases for any signs of damage. Use a case gauge to ensure your cases are sized properly.
- Use a chronograph to measure velocity. This allows you to accurately assess the performance of your loads and confirm that you are not exceeding safe pressure limits.
- Wear appropriate safety gear. Always wear safety glasses, hearing protection, and a reloading bench that can prevent accidental injury.
- Never load more ammunition than you intend to shoot on that range visit.
Step-by-Step Loading Process for .350 Legend with H110:
-
Prepare your cases: Clean and inspect your brass carefully. Deburr, resize, and prime your cases. Ensure the primers are properly seated.
-
Dispense powder: Using a calibrated powder measure and scale, carefully measure and dispense the powder charge. Double-check your measurement. A single grain of powder difference can be dangerous.
-
Seat the bullets: Use a bullet seating die to carefully seat your bullets to the proper depth. Ensure that the bullet is seated consistently and firmly.
-
Crimp the cases: Use a crimp die to crimp the case mouth, securing the bullet in place and providing a consistent, reliable cartridge.
-
Inspect your finished rounds: Thoroughly check each round to confirm that everything is properly seated and that there are no issues that could cause a malfunction.
Sample Load Data (Illustrative Only – Always Refer to the Current Hodgdon Manual):
| Bullet Weight (grains) | Bullet Type | H110 Powder Charge (grains) | Primer Type | Velocity (fps) (Approximate) | Notes |
|---|---|---|---|---|---|
| 147 | Jacketed Hollow Point | 19.5 | Small Rifle | 2100 | This is EXAMPLE DATA. Use Hodgdon's Manual |
| 150 | Jacketed Soft Point | 20.0 | Small Rifle | 2150 | This is EXAMPLE DATA. Use Hodgdon's Manual |
| 180 | Jacketed Soft Point | 21.0 | Small Rifle | 2200 | This is EXAMPLE DATA. Use Hodgdon's Manual |
Disclaimer: This data is for illustrative purposes only. You MUST consult the current Hodgdon Reloading Manual for precise load data specific to your components and equipment. Failure to do so could result in dangerous over-pressure, equipment damage, or injury.
Troubleshooting and Common Issues:
- High Pressure Signs: Excessive primer flow, flattened primers, or cases sticking to the chamber indicate excessive pressure. Immediately stop loading and reduce your powder charge.
- Inconsistent Accuracy: Inconsistent bullet seating depth or powder charges can negatively impact accuracy. Double-check your equipment and technique.
- Poor Case Neck Tension: Ensure proper case neck tension to prevent bullet setback.
Conclusion:
Loading .350 Legend ammunition with H110 can yield excellent results, but it requires meticulous attention to detail and a thorough understanding of safe reloading practices. Always prioritize safety and consult the latest Hodgdon reloading manual before attempting any reloading. Remember, proper reloading techniques and the use of up-to-date load data are essential for safe and successful shooting. Failure to follow these instructions could result in serious injury or death.
