Precision expanding mandrel die for 6.5mm brass preparation. Features stainless steel construction, interchangeable mandrels, and a cutout design for easy case alignment. Made in the USA.
The L.E. Wilson Expanding Mandrel Die is an essential tool for reloaders who demand uniformity and precision. This die prepares new brass by expanding the case neck to slightly under bullet diameter, ensuring consistent neck tension and reliable seating depth shot after shot.
New brass often arrives with inconsistent neck dimensions from bulk shipping. This die corrects those variations, preparing your cases for optimal bullet seating. The result is tighter velocity spreads, improved accuracy, and more predictable ballistics downrange.
Includes one 6.5mm mandrel. Additional mandrels for other calibers are available separately.
