Introduction:
The .38 Super Auto cartridge, a powerful and accurate round, has earned a loyal following among handloaders. Its versatility, suitable for both target shooting and self-defense, makes it a popular choice. However, reloading .38 Super requires precision and a thorough understanding of reloading data. This guide provides comprehensive information, helping you safely and effectively reload .38 Super ammunition. Remember: Always consult your specific reloading manual and prioritize safety. This information is for educational purposes and should not be considered a substitute for manufacturer's instructions.
Understanding .38 Super Reloading
Before diving into specific data, let's grasp the fundamentals. Reloading involves carefully assembling ammunition components: primers, powder, bullets, and cases. Accuracy and safety depend on using the correct components and meticulously following loading data specific to your chosen bullet weight, powder type, and equipment.
Key Components:
- Cases: Ensure your cases are properly sized and cleaned. Consistent case preparation is crucial for reliable reloading.
- Primers: Use primers designed for the .38 Super cartridge. Incorrect primer usage can lead to dangerous malfunctions.
- Powder: Choose a powder appropriate for .38 Super. Different powders burn at different rates, impacting pressure and velocity. Never substitute powders without consulting a reloading manual.
- Bullets: Bullet weight is a significant factor in determining the appropriate reloading data. Weight variations require different powder charges.
Equipment Essentials:
Safe and successful reloading necessitates the right tools:
- Reloading Press: A reliable press is essential for consistent case preparation and assembly.
- Case Sizing Die: Ensures proper case sizing for consistent chambering.
- Powder Measure: Accurate powder measurement is critical for safety and performance. A scale is recommended to double-check powder charges.
- Bullet Seating Die: Sets the bullet to the correct depth and ensures consistent performance.
- Crimping Die: Forms a secure crimp on the case mouth, holding the bullet firmly in place.
Reloading Data for Common .38 Super Bullets
The following table provides sample reloading data for common .38 Super bullet weights. This is not an exhaustive list and should not replace data found in your reloading manual. Always check your manual for the most up-to-date and accurate information. Data is presented as a starting point and should be worked up gradually, always checking for pressure signs. Remember to use a chronograph for accurate velocity measurements.
| Bullet Weight (grains) | Powder Type | Powder Charge (grains) | Primer | COL (inches) | Notes |
|---|---|---|---|---|---|
| 115 | Power Pistol | 4.8 - 5.2 | CCI 500 | 1.125 | Start low, work up |
| 124 | Unique | 4.5 - 4.9 | Winchester Small Pistol | 1.130 | |
| 125 | Bullseye | 5.0 - 5.4 | Federal Small Pistol | 1.125 | |
| 127 | Titegroup | 4.7 - 5.1 | Remington Small Pistol | 1.135 | |
| 130 | AutoComp | 5.2 - 5.6 | CCI 300 | 1.130 |
Note: COL refers to Cartridge Overall Length. Variations in bullet shape and seating depth may require adjustments.
Working Up a Load:
Never jump straight to the maximum load listed in a reloading manual. The process of working up a load is essential for safety and accuracy:
- Start with the minimum listed charge.
- Fire 3-5 rounds at the minimum charge.
- Gradually increase the powder charge in small increments (0.2-0.3 grains).
- Carefully inspect your brass and cases after each increment. Look for signs of excessive pressure such as flattened primers, bulged cases, or excessive ejector marks.
- Do not exceed the maximum listed charge.
Safety First: Avoiding Dangerous Reloading Practices
Reloading is intrinsically safe if performed correctly. However, mistakes can be catastrophic. Always follow these safety guidelines:
- Consult your reloading manual: This is the most important rule. Every powder and bullet combination has unique loading data.
- Double-check your powder charges: Use a scale to verify each powder charge. Mis-measuring powder can be devastating.
- Wear safety glasses: Protect your eyes from accidental powder spills or malfunctions.
- Work in a well-ventilated area: Gunpowder produces fumes.
- Store your reloading components safely: Keep ammunition, powder, and primers securely locked away from children and unauthorized access.
- Clean your equipment regularly: Cleanliness prevents malfunctions and misfires.
