L.E. Wilson’s Neck Sizing Bushings are designed for use with Wilson neck sizing dies and full length sizing dies, allowing reloaders to precisely control neck tension for consistent bullet seating and improved accuracy.
These bushings are essential for precision reloaders and competitive shooters who demand repeatable performance and the ability to fine-tune their reloading setup.
Control Neck Tension for Precision Reloading
Neck tension plays a critical role in bullet seating consistency and overall accuracy. By selecting the correct bushing size, reloaders can achieve uniform bullet grip and consistent performance across every round.
- Provides precise neck sizing control
- Improves consistency in bullet seating
- Supports accuracy and repeatability
- Reduces variation between cartridges
Compatible with Wilson Sizing Dies
These bushings are designed to work seamlessly with Wilson sizing dies, offering flexibility across different reloading setups.

How to Choose the Correct Bushing Size
Selecting the correct bushing size is critical for achieving proper neck tension. There are two common methods used by reloaders:
Method 1: Using a Loaded Round
Measure the diameter of a loaded round at the neck where the bullet sits, then subtract .002 to .003 to determine the correct bushing size.
- Example: .268 – .002 = .266 bushing
Method 2: Using Neck Wall Thickness
- Measure neck wall thickness and multiply by 2
- Add bullet diameter
- Subtract .002 to .003 for proper tension
Example:
- Wall Thickness: .012 × 2 = .024
- Bullet Diameter: .243
- .243 + .024 = .267
- .267 – .003 = .264 bushing
Why Neck Sizing Bushings Matter
- Fine-tune neck tension for different loads
- Improve consistency and accuracy
- Reduce brass working compared to expander systems
- Support precision load development
The Neck Sizing Bushing is a critical component for reloaders looking to maximize control and performance in their reloading process.
