Hodgdon Longshot is a popular extruded powder known for its exceptional performance in various rifle cartridges, particularly those with a magnum-like velocity. Understanding and utilizing the correct Hodgdon Longshot reloading data is crucial for safety and optimal results. This comprehensive guide explores everything you need to know about this powerful powder, from its characteristics to safe reloading practices.
Understanding Hodgdon Longshot Powder
Hodgdon Longshot is an extruded powder, meaning it's formed into cylindrical grains through a die extrusion process. This gives it specific characteristics that differentiate it from other powder types:
- High Density: Longshot boasts a high density, allowing for a large amount of propellant to fit into a given case volume. This translates to higher velocities and flatter trajectories.
- Consistent Burning Rate: Extruded powders like Longshot are generally known for their consistent burning rate, providing predictable performance from shot to shot. This consistency is vital for accuracy.
- Magnum Calibers: It is designed primarily for use in larger-capacity rifle cartridges, making it ideal for magnum calibers and other high-performance rounds.
- Temperature Stability: While all powders are affected by temperature, Longshot exhibits relatively good temperature stability compared to some other propellants. However, you should still always be aware of environmental conditions.
Caution: Always consult the official Hodgdon reloading manual for the most accurate and up-to-date data for your specific cartridge and bullet combination. Never exceed the maximum loads listed in any reloading manual.
Hodgdon Longshot Reloading Data: Key Considerations
Before diving into specific data, let's discuss essential factors to consider when using Hodgdon Longshot:
- Primer Type: The type of primer (small rifle, large rifle, magnum) significantly impacts ignition and overall performance. Always use the primer type specified in the Hodgdon manual.
- Bullet Weight: Heavier bullets generally require more powder to reach optimal velocity. Conversely, lighter bullets may need less powder.
- Case Capacity: The internal volume of your cartridge case influences the amount of powder that can be safely accommodated.
- Bullet Type: Different bullet types (e.g., jacketed, lead) can affect pressure and accuracy. Using the wrong type of bullet with your chosen load can be extremely dangerous.
- Equipment: Proper reloading equipment, including a scale that measures in increments of 0.1 grains or better, is essential for consistent results and safety. A good powder measure, case trimmer and press are also critical.
Finding the Right Hodgdon Longshot Reloading Data
Hodgdon's official reloading manual is the definitive source of information. This manual contains extensive data tables organized by cartridge and bullet weight. The data generally includes:
- Bullet Weight: The weight of the projectile in grains.
- Powder Charge: The recommended amount of Hodgdon Longshot powder in grains.
- Primer Type: The type of primer recommended.
- Velocity: The expected muzzle velocity in feet per second (fps).
- Pressure: The expected peak chamber pressure in PSI (pounds per square inch). Never exceed maximum pressure limits.
Example Data Table (Illustrative - Not Actual Data):
| Cartridge | Bullet Weight (gr) | Powder Charge (gr) | Primer Type | Velocity (fps) | Pressure (PSI) |
|---|---|---|---|---|---|
| .300 Winchester Magnum | 180 | 70 | Large Rifle Magnum | 2850 | 60,000 |
| .300 Winchester Magnum | 180 | 72 | Large Rifle Magnum | 2900 | 62,000 |
| .300 Winchester Magnum | 200 | 73 | Large Rifle Magnum | 2750 | 59,000 |

Safety First: Reloading with Hodgdon Longshot
Reloading ammunition is inherently dangerous if not done correctly. Always follow these safety precautions:
- Consult the Manual: Always start with the minimum charge listed in the Hodgdon manual and work your way up gradually.
- Wear Safety Glasses and Hearing Protection: Eye and hearing protection are essential to prevent injury.
- Cleanliness: Maintain a clean workspace and ensure your equipment is properly functioning.
- Careful Measurement: Use a precise scale to measure powder charges. Never estimate.
- Single-Stage Reloading: For beginners, a single-stage press is recommended to promote better control and accuracy.
- Regular Inspection: Inspect your loaded ammunition for any defects or inconsistencies.
- Proper Storage: Store your loaded ammunition safely and securely, away from children and unauthorized access.
Conclusion: Mastering Hodgdon Longshot
Hodgdon Longshot is a powerful and versatile powder, but its effectiveness and safety depend on meticulous attention to detail. By understanding its characteristics, consulting the official reloading manual, and adhering to strict safety protocols, you can safely and successfully use Longshot to produce accurate and high-performance ammunition. Remember, safety should always be your top priority when reloading ammunition. Improper reloading practices can lead to serious injury or death. Always double check your work, and if you have any doubts, consult with an experienced reloader.
