Finding the right bushing for your MEC reloading press and Alliant powder can feel like navigating a maze. This guide aims to simplify the process, providing you with a comprehensive understanding of MEC bushings and how they interact with various Alliant powders for consistent and safe reloading. We'll explore the importance of bushing selection, delve into specific Alliant powder recommendations, and offer tips for achieving optimal results.
Understanding MEC Bushing Functionality
Before jumping into specific powder and bushing pairings, let's clarify the role of the bushing in your MEC reloading process. The bushing acts as a metering device, controlling the precise amount of powder dropped into each shotshell hull. Different bushings have varying internal diameters, resulting in different powder charges. Using the incorrect bushing can lead to inconsistent loads, potentially dangerous over-charges, or under-charges leading to unreliable performance.
Why Accurate Metering is Crucial
Precise powder measurement is paramount in shotshell reloading. Inconsistent powder charges can lead to:
- Inconsistent shot patterns: Variations in powder charge directly impact the velocity and thus the shot pattern of your shells.
- Increased pressure: Over-charges can result in dangerously high pressures, potentially damaging your firearm or causing injury.
- Reduced performance: Under-charges lead to underpowered shells, reducing their effectiveness in the field.
Alliant Powder Recommendations & MEC Bushing Equivalents
This section provides general guidance. Always refer to your specific Alliant powder data and the MEC bushing chart provided with your reloading press for precise bushing selection. The values below serve as an illustrative example and may not be universally applicable.
| Alliant Powder | Typical Shotshell Application | Approximate MEC Bushing Size (Gauge Dependent - Verify with your press's manual) | Notes |
|---|---|---|---|
| Alliant Unique | Various Shotshell Loads | #28 - #32 (Example) | Known for its versatility, but bushing size varies significantly with load data. |
| Alliant Red Dot | Light Target Loads | #28 - #30 (Example) | Often used for lighter loads, requires careful bushing selection. |
| Alliant Steel | Steel Shot Loads | #30 - #34 (Example) | Designed for steel shot, may require larger bushings due to steel's weight. |
| Alliant Promo | Target Loads, various shots | #29 - #33 (Example) | Requires precise bushing selection for optimal results. |
| Alliant Clays | Target Loads, Light Field Loads | #26 - #30 (Example) | Suitable for a range of applications, but bushing selection is critical. |
Important Considerations:
- Gauge: Bushing sizes are gauge-specific. A bushing suitable for 12-gauge will not work for 20-gauge.
- Powder type: Different powders have different densities, affecting how much powder a given bushing will meter.
- Environmental factors: Temperature and humidity can affect powder flow and, consequently, the accuracy of your bushing.
- Always Double Check: Before using any bushing, always cross-reference the selected bushing with your reloading manual.
Advanced Tips for Accurate Metering:
- Start with the recommended bushing size: Begin with the bushing size suggested by Alliant and your MEC press manual. Gradually adjust as needed.
- Test your loads: Carefully weigh each charge to verify consistent powder drop.
- Consistent powder handling: Ensure consistent handling of your powder to prevent clumping or bridging.
