Expander Mandrels – Precise Clamping and Consistent Reloading
 Each set includes two mandrels , one with a diameter reduction of -0.001 inch and the other of -0.002 inch . These very precise tolerances allow you to achieve optimal bullet tension and ensure consistent results in your reloading process.
 Using an expander mandrel in your reloading protocol offers many essential advantages for long-range shooting and load repeatability :

 Improved ball seat
 The expander mandrel allows for precise enlargement of the neck's internal diameter, ensuring perfect alignment and a uniform grip on the bullet. The result: optimal centering , less runout , and improved accuracy on target .

 Fine control of collar tension
 Using the expander mandrel allows you to precisely adjust the tension applied to the bullet . This is crucial in long-range shooting , as it directly influences the consistency of the bullet's release and therefore its ballistic performance.

 Blood pressure regularity
 The mandrels ensure constant tension from case to case , resulting in a uniform bullet start, better chambering , and consistent accuracy shot after shot .

 Compatible with thermal machining (collar annealing)
 Combined with proper annealing, mandrels help maintain consistent tension , even after multiple reloading cycles. This extends case life while ensuring exemplary consistency.

 Customization & versatility
 Available in different diameters, the mandrels adapt to each type of bullet and case , allowing you to customize the tension according to your needs (weight, load, PRS use, hunting, etc.).

 Reloading efficiency
 With uniform tension ensured by the chuck, you reduce the need for subsequent adjustments and gain speed and consistency during your reloading sessions.
