Quick Tip: How To Use L.E. Wilson Bushing Dies

This guide explains the function and setup of L.E. Wilson bushing dies for reloading. It details how bushing dies offer adjustable neck sizing by using interchangeable bushings, which is crucial for managing varying brass neck thicknesses across different manufacturers and calibers. The process involves measuring the cartridge neck, selecting a bushing (typically 0.001" to 0.003" smaller than the loaded cartridge neck diameter), inserting it into the die, and setting the stem to allow for slight float. This method helps improve case concentricity and consistency, especially for precision shooting applications.

Quick Summary

L.E. Wilson bushing dies offer precise neck sizing by using interchangeable bushings to compensate for varying brass neck thicknesses. To set up, select a bushing 0.001-0.003" smaller than your loaded cartridge neck, insert it, and back off the die stem 1/16-1/8" after contact to allow self-leveling for improved concentricity and accuracy.

Frequently Asked Questions

What is the main advantage of using bushing dies for reloading?

The primary advantage of bushing dies is their ability to precisely control neck tension by using interchangeable bushings. This allows reloaders to compensate for variations in case neck wall thickness between different brass manufacturers, leading to more consistent neck sizing and improved accuracy.

How do I determine the correct bushing size for my reloads?

To select a bushing, first measure the neck diameter of a loaded cartridge with calipers. Then, choose a bushing that is typically 0.001 to 0.003 inches smaller than this measurement. This difference creates the desired neck tension for holding the bullet securely.

How should I set up an L.E. Wilson bushing die?

After inserting the chosen bushing, screw the die stem down until it contacts the bushing. Then, back the stem off approximately 1/16 to 1/8 of a turn. This slight looseness allows the bushing to float and self-level on the case neck, promoting better concentricity.

Why is it important to minimize brass work when resizing case necks?

Excessive brass work during neck resizing can harden the case neck, leading to inconsistencies in bullet concentricity and muzzle velocity. Using bushing dies allows for less aggressive resizing, preserving the brass and improving the uniformity of your reloaded ammunition.
