The Lee Six Pack is a popular choice for 9mm reloading, offering efficiency and affordability. However, like any reloading tool, occasional problems can arise. One common issue is indexing problems, where the case isn't properly aligned in the sizing die, leading to inconsistent results. This article will delve into the common causes of indexing problems with the Lee Six Pack 9mm and provide solutions to get you back to smooth, reliable reloading.
Understanding the Lee Six Pack Indexing Mechanism
Before troubleshooting, it's essential to understand how the Lee Six Pack's indexing system works. The cases are held by a collet that grips the case mouth. As the handle is rotated, the case is advanced through the sizing die. Proper indexing ensures the case is correctly aligned for uniform sizing and consistent bullet seating. If the indexing isn't working correctly, the case may be improperly seated or even damaged.
Common Causes of Lee Six Pack 9mm Indexing Problems
Several factors can contribute to indexing issues with the Lee Six Pack 9mm:
1. Case Mouth Issues:
- Irregular Case Mouths: Cases with damaged or uneven case mouths may not be gripped securely by the collet. This can lead to slippage and improper indexing. Inspect your brass for any damage and consider trimming or deburring as necessary.
- Dirty Case Mouths: Lubricant or other debris on the case mouth can prevent the collet from gripping the brass firmly. Always ensure your brass is clean before reloading.
- Incorrect Collet Tension: The collet's grip on the case mouth needs to be firm but not excessively tight. Too loose a grip causes slippage, while too tight a grip can damage the case mouth or even the collet itself.
2. Lee Six Pack Setup and Maintenance:
- Die Adjustment: Improperly adjusted sizing die can contribute to indexing issues. Ensure the die is properly seated and adjusted according to Lee's instructions.
- Shell Plate Issues: A bent or damaged shell plate can prevent the cases from properly indexing. Carefully inspect the shell plate for any damage or warping.
- Worn or Damaged Parts: Over time, the collet, shell plate, or other components can wear out, leading to indexing problems. Regularly inspect your equipment for any signs of wear and tear and replace any worn parts as needed.
- Lubrication: Insufficient or improper case lubrication can lead to increased friction and indexing issues. Use a suitable case lubricant and ensure it's applied evenly.
3. Brass Quality:
- Mixed Brass: Reloading with mixed brass from different manufacturers can lead to inconsistencies in case dimensions and indexing problems. Stick to brass from a single manufacturer for the best results.
Troubleshooting Steps for Lee Six Pack 9mm Indexing Problems
-
Inspect Your Brass: Begin by carefully inspecting your brass for any damage, dirt, or inconsistencies in the case mouths. Clean and deburr any damaged cases.
-
Check Collet Tension: Ensure the collet is gripping the case mouth firmly but not excessively tight. Experiment with slight adjustments to find the optimal tension.
-
Verify Die Adjustment: Double-check the sizing die adjustment according to Lee's instructions. Incorrect adjustment can lead to binding and indexing problems.
