Lee's collet neck sizing die for 7mm PRC uses a precision mandrel and collet system to minimize runout without lubrication. Perfect for handloaders seeking consistent case neck alignment.
The Lee Collet Neck Sizing Die represents a straightforward approach to one of handloading's most critical tasks: achieving consistent case neck concentricity.
This die employs a collet that squeezes around a mandrel, gently sizing your case neck while maintaining precise alignment. The result is reduced runout—the wobble that can affect accuracy and consistency.
Consistent case neck alignment directly influences bullet seating consistency and, ultimately, accuracy. By sizing only the neck and minimizing runout, you're taking a significant step toward tighter groups and more predictable ballistics.
This die is ideal for precision rifle handloaders who understand that attention to detail in case preparation pays dividends downrange.
