Wilson Expanding Mandrel 6.5mm Sizing Die
L.E. Wilson expanding mandrel die for 6.5mm brass preparation. Ensures consistent neck diameter on new cases, improves seating depth consistency, and reduces shipping damage. Includes one mandrel; fits standard 7/8" reloading press.
Prepare Your Brass the Right Way
The Wilson Expanding Mandrel Sizing Die is a specialized reloading tool designed to condition new brass cases before the seating operation. This die addresses a common problem in reloading: new brass cases often arrive with inconsistent neck dimensions and damage from bulk shipping.
Why Use an Expanding Mandrel?
Proper neck preparation is fundamental to consistent ammunition. When you run new brass through an expanding mandrel, you achieve:
- Uniform neck diameter across all your cases
- Consistent neck tension for more predictable bullet seating
- Improved shot-to-shot consistency from proper seating depth control
- Damage correction from shipping and handling
Design Features
Wilson engineered this die with the reloader in mind:
- Cut-out viewing window makes case alignment and depth setting straightforward
- Interchangeable mandrels allow you to use the same die body for multiple calibers
- Stainless steel components resist corrosion and wear
- Precision expansion to slightly under bullet diameter for proper tension
- Standard 7/8" press compatibility fits your existing reloading setup
- Wilson-manufactured lock nut (.225" thickness, .270" height, 1.250" OD) ensures secure positioning
What's Included
This package includes one 6.5mm mandrel. Additional mandrels for other calibers are sold separately, making this a versatile addition to your reloading bench.
For handloaders who demand consistency and precision, the Wilson Expanding Mandrel Die is a worthwhile investment in ammunition quality.
