Introduction:
Reloading your own 20 gauge ammunition offers several advantages: cost savings, the ability to tailor loads to specific needs (like reduced recoil for clays or increased power for hunting), and the satisfaction of crafting your own ammo. However, safe and effective reloading requires precise data. This guide delves into the crucial aspects of 20 gauge reloading data, covering everything from choosing components to understanding safety precautions. We'll explore various powder types, shot sizes, and primers, providing a foundation for responsible and successful reloading. Remember: always consult your reloading manual and follow its instructions meticulously. This guide is for informational purposes only and doesn't replace the need for a dedicated reloading manual.
Understanding 20 Gauge Reloading Components
Before diving into specific data, let's review the key components involved in 20 gauge reloading:
1. Shot Shells: The Foundation
Choosing the right hulls is crucial. Different manufacturers produce hulls with varying specifications affecting their capacity and suitability for different loads. Factors to consider include:
- New vs. Once-Fired: New hulls are consistent and generally preferred, while once-fired hulls might require more careful inspection for damage.
- Material: Most 20 gauge hulls are made of plastic, offering durability and ease of reloading.
- Gauge: Ensure you're using 20 gauge hulls. Never attempt to reload hulls of a different gauge.
2. Powder: The Driving Force
Powder selection directly impacts the pressure and velocity of your load. The wrong powder can lead to unsafe pressures or poor performance. Popular choices for 20 gauge include:
- Clays: A popular choice for target loads due to its consistent burning rate and relatively low recoil.
- Unique: Another versatile powder suitable for various 20 gauge loads, offering a balance of power and cleanliness.
- International Clays (IMR): Similar to Clays but offering slightly different performance characteristics.
Note: Always use powder specifically recommended for shotshells. Rifle or pistol powders are unsuitable and extremely dangerous in shotgun shells.
3. Wads: Cushioning the Shot
Wads are crucial for properly sealing the shot and preventing gas blowback. Choosing the correct wad for your load and hull is essential for consistent performance and safety. Different wad types exist, including:
- Fiber Wads: Traditional wads offering good performance.
- Plastic Wads: Modern wads designed for better sealing and performance.
Ensure the wad is compatible with your chosen hull and powder.
4. Shot: The Payload
Shot size selection depends on the intended use:
- Smaller Shot Sizes (e.g., #7.5, #8): Ideal for target shooting, offering a denser pattern.
- Larger Shot Sizes (e.g., #4, #6): Suitable for hunting, providing greater stopping power.
The quantity of shot impacts the pressure and recoil of the load.
5. Primers: Initiating the Explosion
Shotgun primers are specifically designed for shotshells and come in various types. Common types include:
- Standard Primers: Suitable for most 20 gauge loads.
- Magnum Primers: Often used with heavier loads or slower burning powders.
Ensure your chosen primers are compatible with your powder and load data.

Disclaimer: The data below is a simplified example only and should never be used for actual reloading. Always consult a reputable reloading manual specific to your components. Incorrect data can lead to catastrophic equipment failure and serious injury.
Powder | Shot Size | Shot Weight (oz) | Wad | Primer | Case | Pressure (psi) | Velocity (fps) |
---|---|---|---|---|---|---|---|
Clays (example) | #8 | 7/8 | Example Wad | Standard | Example Hull | Example Pressure (Consult Manual!) | Example Velocity (Consult Manual!) |
Unique (example) | #6 | 1 | Example Wad | Standard | Example Hull | Example Pressure (Consult Manual!) | Example Velocity (Consult Manual!) |
Safety Precautions: Paramount Importance
Reloading is inherently dangerous. Following these safety precautions is paramount:
- Always wear safety glasses and ear protection.
- Use a properly maintained reloading press.
- Follow your reloading manual meticulously.
- Never exceed the maximum pressure listed in your manual.
- Inspect your loaded shells carefully before use.
- Store ammunition properly.
- Never mix components or use outdated data.
Conclusion: Responsible Reloading
Reloading 20 gauge ammunition offers significant benefits, but only when undertaken responsibly. This guide provides a foundational overview. The most important step is obtaining and meticulously following a trusted reloading manual specific to your chosen components. Remember that safety is paramount, and always prioritize safe practices over convenience or cost savings. Safe and successful reloading requires diligence, patience, and a commitment to learning and following best practices. Always double-check your work and never compromise on safety.
