The Wilson Expanding Mandrel Sizing Die is used to prepare new brass cases for seating, ensuring consistent neck diameter and improving seating depth consistency.
Each die includes one mandrel with additional mandrels available separately, and features a cutout for easy case alignment and depth setup.
Designed to fit standard 7/8ths reloading presses, the die expands the neck slightly under bullet diameter and is made of stainless parts for durability and accuracy.
