Description
The L.E. Wilson Expanding Mandrel Die is an essential tool for precision reloaders working with .223 caliber ammunition. Designed to prepare new brass for optimal bullet seating, this die ensures a consistent neck diameter by expanding the case neck to slightly under bullet diameter, achieving uniform neck tension and consistent seating depth.
Crafted from stainless steel for long-lasting durability, the die features interchangeable mandrels (sold separately) to accommodate various calibers. A unique cut-out in the die provides a clear view for aligning the case and accurately setting the depth. Compatible with standard 7/8ths reloading presses, the die includes a lock nut manufactured by L.E. Wilson for added precision.
This expanding mandrel die is particularly beneficial for new brass that may be damaged during bulk shipping or for properly preparing cases for their first firing. Proudly made in the USA, the L.E. Wilson Expanding Mandrel Die offers exceptional quality and precision, making it a reliable addition to any reloader’s toolkit.
Includes one mandrel; additional mandrels are sold separately.
