The .22 Hornet is a beloved cartridge among hunters and target shooters for its accuracy, manageable recoil, and versatility. Its relatively low pressure allows for a wide range of handloads, making it perfect for those interested in reloading their own ammunition. This guide will provide comprehensive .22 Hornet load data, safety precautions, and advice to ensure safe and effective reloading. Remember, always prioritize safety when working with firearms and reloading components.
Understanding .22 Hornet Cartridge Characteristics
Before diving into load data, it’s crucial to understand the .22 Hornet's specifications:
- Caliber: .22 (5.6mm)
- Case Type: Rimmed
- Typical Bullet Weights: 30-50 grains
- Typical Powder Charges: Vary greatly depending on bullet weight and powder type (see detailed load data below).
- Maximum Average Pressure (MAP): Typically around 30,000 PSI (this can vary slightly based on manufacturer specifications). Never exceed the manufacturer's recommended maximum pressure.
It's essential to consult your specific reloading manual for the most accurate and up-to-date pressure data for your particular components. This guide serves as a starting point, but should never replace a comprehensive reloading manual.
Essential Reloading Equipment and Components
Before you begin, ensure you have the necessary equipment and components:
- Reloading Press: A single-stage or progressive press is suitable.
- Dies: A full set of .22 Hornet dies (sizing die, powder measure, bullet seating die, and crimp die).
- Powder Measure: A precise powder measure is critical for consistent loads.
- Case Gauge: Used to check case dimensions after sizing.
- Scale: An accurate scale for measuring powder charges (within 0.1 grain accuracy).
- Bullet Puller: For removing bullets from cases if necessary.
- Case Preparation Tools: For cleaning and preparing brass cases.
- .22 Hornet Brass: High-quality brass cases are vital.
- Bullets: Choose bullets appropriate for your intended use (e.g., hunting, target shooting).
- Gunpowder: Select a powder appropriate for the .22 Hornet (see examples below). Consult your reloading manual for recommended powders.
- Primers: Small rifle primers are required.
Sample 22 Hornet Load Data
Disclaimer: The following data is for informational purposes only and is not a substitute for a comprehensive reloading manual. Always consult your reloading manual for load data specific to your components and equipment. This data is based on commonly used components and should be considered a starting point for load development.
| Bullet Weight (grains) | Powder Type | Powder Charge (grains) | Primer | COL (inches) | Notes |
|---|---|---|---|---|---|
| 35 | IMR 4198 | 12.0 - 13.0 | CCI Small Rifle | 1.200 | Start low, work up gradually |
| 40 | Accurate 2230 | 13.5 - 14.5 | CCI Small Rifle | 1.225 | Work up carefully |
| 45 | Unique | 11.0 - 12.0 | CCI Small Rifle | 1.250 | Accurate load for hunting |
| 46 | Power Pistol | 10.5 - 11.5 | CCI Small Rifle | 1.255 | Good velocity load |
COL: Cartridge Overall Length. This measurement should be checked carefully with your specific bullets and cases.
Note: This table shows a range of powder charges. You must start at the minimum charge and work up gradually, carefully monitoring pressure signs. Never exceed the maximum listed charge in your reloading manual.
Safety Precautions: Absolutely Essential!
Reloading ammunition is inherently dangerous. Failure to follow safety procedures can result in serious injury or death.
- Always wear safety glasses: Eye protection is non-negotiable.
- Work in a well-ventilated area: Gunpowder fumes can be harmful.
- Never mix different types of gunpowder: This can be extremely dangerous.
- Measure powder charges carefully: Accuracy is paramount.
- Double-check your work: Verify each step before proceeding.
- Inspect your cartridges carefully: Look for any defects before loading into your firearm.
- Never load a cartridge that is not properly seated or crimped.
- Never exceed the maximum listed pressure in your reloading manual.
- Store ammunition properly: Keep ammunition away from children and in a cool, dry place.
Load Development: A Gradual Process
Load development is a crucial part of reloading. It involves incrementally increasing the powder charge to find the best combination of accuracy and velocity for your specific firearm and components.
- Start Low: Always begin with the minimum charge listed in your reloading manual.
- Work Up Gradually: Increase the powder charge in small increments (0.1 to 0.3 grains).
- Observe Pressure Signs: Watch for signs of excessive pressure, such as flattened primers, excessive case expansion, or unusually loud reports. If any of these signs are present, stop immediately.
- Chronograph Your Loads: A chronograph will help you measure the velocity of your loads. This information will assist in identifying your optimal load.
- Accuracy Testing: Test your loads at the range to evaluate accuracy.
Remember, load development is a personal journey, and finding the perfect load for your rifle will take time and careful observation.
Conclusion
Reloading .22 Hornet ammunition offers several advantages, including cost savings and the ability to tailor loads to your specific needs. However, reloading is not without risk. By understanding the process, following safety precautions meticulously, and utilizing reliable load data, you can safely enjoy the benefits of reloading your own .22 Hornet ammunition. Always consult your manual, start low, and work up carefully. Safe and accurate reloading!
