Hornady Lock-N-Load bushings are essential components for the Hornady Lock-N-Load progressive reloading presses. These small but crucial parts dictate the amount of powder dropped into each cartridge case, ensuring consistent and accurate reloading. Understanding Hornady Lock-N-Load bushings is key to safe and successful ammunition reloading. This guide will delve into their function, selection, use, and troubleshooting.
Understanding Hornady Lock-N-Load Bushings and Their Function
Hornady Lock-N-Load bushings are small, cylindrical components with precisely machined bores. They fit into the powder measure of the Hornady Lock-N-Load press. The bushing's bore size determines the volume of powder dispensed with each press cycle. This ensures consistent powder charges, critical for maintaining accurate and safe ammunition. Different bushing sizes correspond to different powder volumes, allowing reloaders to fine-tune their powder charges to specific cartridge types and loads.
Key Function: The primary function of a Hornady bushing is to control the powder charge. The press's powder measure draws powder up into a cavity, the bushing then restricts the flow of powder, ensuring that a consistent amount is dispensed for each round. Improper bushing selection can lead to inaccurate powder charges, potentially causing dangerous over- or under-charges.
Selecting the Right Hornady Lock-N-Load Bushing
Choosing the correct Hornady bushing is crucial for safe and accurate reloading. Hornady provides comprehensive charts that match bushings to various powders and cartridges. These charts consider the powder's flow characteristics and the cartridge's case capacity. Never guess; always consult the Hornady manual or their online resources to find the appropriate bushing for your specific needs.
Factors Affecting Bushing Selection:
- Powder Type: Different powders have different flow rates and densities. A bushing appropriate for one powder may not be suitable for another.
- Cartridge Type: Case capacity significantly impacts the required powder charge and, consequently, the appropriate bushing size.
- Desired Powder Charge: The desired powder charge dictates the required bushing size. Hornady's charts often list multiple bushings for a single load, allowing for adjustments based on preference or specific needs.
Finding the Right Bushing: Hornady's website and reloading manuals contain extensive charts and resources to help you find the perfect bushing size. They often categorize bushings by number, with higher numbers representing larger powder charges.
Using Hornady Lock-N-Load Bushings: A Step-by-Step Guide
Using Hornady bushings is straightforward but requires precision and attention to detail. Incorrect installation or handling can result in inaccurate powder charges and safety risks.
Steps:
- Consult the Manual: Always begin by referring to the Hornady reloading manual for your specific press and powder type. This will provide the most accurate and up-to-date information.
- Identify the Correct Bushing: Based on the manual's instructions, select the bushing corresponding to your powder, cartridge, and desired charge.
- Insert the Bushing: Carefully insert the bushing into the powder measure, ensuring a snug fit. A loose fit can lead to inaccurate powder charges.
- Adjust the Powder Measure: Once the bushing is in place, adjust the powder measure according to the instructions in the manual. This often involves a small adjustment screw or knob.
- Test and Verify: Always test your setup with a small number of rounds, carefully weighing each charge to ensure consistency and accuracy. If the charges are inconsistent, troubleshoot the setup before proceeding.
Troubleshooting Common Issues with Hornady Lock-N-Load Bushings
Despite their simplicity, issues can arise when using Hornady bushings. Here are some common problems and troubleshooting tips.
| Problem | Possible Cause | Solution |
|---|---|---|
| Inconsistent Powder Charges | Incorrect bushing size, damaged bushing, loose fit | Double-check bushing size, inspect for damage, ensure a snug fit |
| Powder Bridges | Poor powder flow, incorrect powder measure adjustment | Adjust powder measure, try a different powder, check for obstructions |
| Excessive Powder Drop | Incorrect bushing size, excessive powder measure setting | Recheck bushing size, adjust powder measure downwards, verify powder measure is level |
| Insufficient Powder Drop | Incorrect bushing size, insufficient powder measure setting | Double-check bushing size, adjust powder measure upwards, check for any powder bridging |
Maintaining and Caring for Hornady Lock-N-Load Bushings
Proper maintenance ensures the longevity and accuracy of your bushings.
- Cleaning: Regularly clean the bushings with a brush and compressed air to remove any powder residue.
- Storage: Store bushings in a clean, dry place to prevent damage or corrosion.
- Inspection: Periodically inspect bushings for any damage or wear. Replace any damaged bushings.
Conclusion: Mastering Hornady Lock-N-Load Bushings for Accurate Reloading
Hornady Lock-N-Load bushings are fundamental to precise and safe reloading. By understanding their function, selecting the correct size, and following proper procedures, reloaders can ensure consistent and accurate powder charges. Remember, safety is paramount; always consult the Hornady manual and double-check your work before reloading ammunition. Consistent practice and attention to detail will lead to successful and safe ammunition reloading using Hornady's innovative system.
