Reloading your own 20 gauge ammunition can be a rewarding experience, offering cost savings and the ability to tailor loads to your specific needs. However, it's crucial to prioritize safety and accuracy. This guide provides comprehensive information on 20 gauge load data, but always consult your reloading manual first and follow its instructions precisely. This information is for educational purposes only and should not be considered a substitute for a comprehensive reloading manual.
Understanding 20 Gauge Shell Components
Before diving into load data, let's review the essential components of a 20 gauge shotshell:
-
Hull: The plastic or paper casing that holds everything together. Choosing the right hull is important for proper crimp and consistent performance. Different manufacturers offer hulls with varying characteristics.
-
Primer: Initiates the combustion process. Small rifle primers are typically used in 20 gauge shells.
-
Powder: The propellant that drives the shot charge. The type and amount of powder significantly impact the shell's velocity and pressure. Using the wrong powder can be extremely dangerous.
-
Wads: Separate the powder from the shot and create a gas seal. Different wad types (e.g., felt, plastic) affect shot patterns and performance.
-
Shot: The projectile itself. Shot size and weight vary depending on intended use (e.g., birdshot, buckshot).
Key Considerations for 20 Gauge Reloading
Several factors influence the performance and safety of your 20 gauge reloads:
-
Powder Type and Charge: This is paramount. Using incorrect powder or charge weight can lead to dangerously high pressures, causing catastrophic equipment failure and potential injury. Always double-check your powder charge before loading.
-
Wad Selection: Wads must be compatible with your chosen hull and shot size. Incorrect wad selection can lead to inconsistent patterns or pressure issues.
-
Shot Size and Weight: The size and weight of your shot significantly impact your shotgun's range and effectiveness.
-
Crimp: A proper crimp ensures a consistent seal and prevents the shot from leaking out.
-
Equipment: A proper reloading press, powder measure, and other tools are crucial for safe and accurate reloading.
Sample 20 Gauge Load Data (Illustrative Only)
Disclaimer: The following data is for illustrative purposes only. It is not a substitute for a comprehensive reloading manual specific to your chosen components. Never use this data without consulting your reloading manual. Improper reloading can result in serious injury or death.
This example uses hypothetical components – you must find equivalent data in your reloading manual.
| Primer | Powder | Powder Charge (grains) | Wad | Shot Size/Weight (oz) | Hull | Estimated Velocity (fps) | Estimated Pressure (psi) |
|---|---|---|---|---|---|---|---|
| Small Rifle | Hypothetical Powder A | 16.5 | Hypothetical Wad A | #7.5 / 7/8 | Hypothetical Hull A | 1150 | 10,500 |
| Small Rifle | Hypothetical Powder B | 18.0 | Hypothetical Wad B | #6 / 1 | Hypothetical Hull B | 1250 | 11,000 |
Remember: This is sample data only. You must replace this with data from a reputable reloading manual that specifically matches your components.
Finding Reliable 20 Gauge Reloading Data
Several sources provide accurate and reliable reloading data:
-
Reloading Manuals: These are the primary source for safe and accurate load data. Major manufacturers like Alliant, Hodgdon, and IMR publish detailed manuals.
-
Component Manufacturers: Powder and primer manufacturers often provide load data on their websites, but always cross-reference with a reloading manual.
-
Online Forums (Use Caution): While some online forums can be helpful, always verify information found online with a reputable reloading manual. Never rely solely on online forums for reloading data.
Safety First: Essential Reloading Practices
-
Always wear safety glasses and ear protection while reloading.
-
Work in a clean and well-ventilated area.
-
Double-check your powder charges before loading.
-
Never exceed maximum recommended loads.
-
Regularly inspect your reloading equipment for wear and tear.
-
Take a reloading course from a certified instructor if you are a beginner.
Reloading 20 gauge ammunition can be a safe and enjoyable hobby with proper knowledge, care, and adherence to established safety procedures. However, neglecting safety precautions can have severe consequences. Always prioritize safety and consult reliable sources for accurate load data.
