Reloading your own 20 gauge shotgun shells offers several advantages: cost savings, the ability to tailor loads to specific needs, and the satisfaction of crafting your own ammunition. However, safety and precision are paramount. This guide provides comprehensive information on 20 gauge shotgun reloading data, but remember: always consult your reloading manual and follow its instructions meticulously before attempting to reload any ammunition. This information is for educational purposes only and should not be considered a substitute for proper training and a comprehensive reloading manual.
Understanding 20 Gauge Reloading Components
Before diving into data, let's review the essential components:
-
Shotgun Hulls: These are the empty cases you'll fill. Choose hulls designed for the specific type of shot you plan to use (e.g., steel, lead). Consider the hull's quality and its suitability for your intended purpose (e.g., hunting, clays). Properly sizing the hull to your components is vital.
-
Powder: This is the propellant that launches the shot. This is the most critical component in safe reloading. Use only the powder recommended in your reloading manual for your specific hull, wad, shot, and desired velocity. Incorrect powder charges can lead to dangerous overpressure.
-
Wads: These are placed between the powder and the shot, creating a seal and ensuring proper shot pattern. Wads come in various types and designs (e.g., felt, plastic, fiber), each affecting the performance and patterns of your shots. Using the correct wad size is crucial to avoid obstructions and pressure issues.
-
Shot: This is the projectile. Choose the correct shot size for your intended game or target. Common shot sizes for 20 gauge include #7.5, #8, #9 for upland game birds, and larger sizes for waterfowl or other game. Shot weight significantly impacts the load and its recoil.
-
Primer: This ignites the powder charge. Use primers specifically designed for shotgun shells and compatible with your chosen hull.
20 Gauge Reloading Data Considerations
The following points are crucial when dealing with 20 gauge reloading data:
-
Powder Type and Charge: The most critical aspect. Slight variations can lead to dangerous over-pressure or under-pressure, impacting accuracy and safety. Never deviate from your reloading manual's recommendations.
-
Shot Weight: The weight of the shot directly influences the pressure generated within the hull. Heavier shot requires adjustments to powder charges to maintain safe pressure levels.
-
Wad Type and Size: Different wad types and sizes influence the crimp and the overall pressure. Utilizing an incorrect wad can lead to inconsistent patterns and potential problems.
-
Hull Condition: Reusing hulls multiple times might compromise their integrity and lead to pressure issues. Inspect hulls before each reload for cracks or damage.
-
Crimp: The crimp secures the components and ensures a proper seal. An improper crimp can cause gas leaks and unreliable performance.
Where to Find Reliable 20 Gauge Reloading Data
Always rely on reputable sources for reloading data:
-
Manufacturer's Reloading Manuals: Powder manufacturers like Alliant, Hodgdon, and IMR provide comprehensive manuals with specific data for their powders. These manuals should be your primary source.
-
Reputable Reloading Guides: Several books and online resources offer data, but always cross-reference with manufacturer's manuals.
-
Experienced Reloaders: Learning from experienced and knowledgeable reloaders can be invaluable. However, always double-check their data against manufacturer's guidelines.
Safety First!
-
Never exceed maximum recommended powder charges. Overloading is extremely dangerous and can result in catastrophic equipment failure, injury, or death.
-
Always wear safety glasses and hearing protection while reloading.
-
Store your reloading components properly and keep them away from children.
-
Invest in a quality reloading press and follow proper reloading techniques.
-
Regularly inspect your equipment for wear and tear.
This guide provides a foundation for understanding 20 gauge shotgun reloading. Remember, safe and accurate reloading requires careful attention to detail, diligent research, and a deep understanding of the process. Consult your reloading manual, follow its instructions precisely, and prioritize safety above all else.
