The L.E. Wilson Die with Expanding Mandrel in .256'' is a purpose-built neck-preparation tool for handloaders who demand consistency shot after shot. Whether you're working with new brass straight from bulk packaging or preparing fired cases for a fresh reload, this expanding mandrel die ensures uniform neck tension and repeatable bullet seating depth—two cornerstones of accurate reloading. The .256'' mandrel fits standard 7/8"-threaded reloading presses, making it compatible with virtually any conventional progressive, turret, or single-stage setup you're already running.

Precision reloading hinges on neck prep, and L.E. Wilson's design addresses this directly. The die expands the case neck to slightly under bullet diameter, creating the consistent grip that translates to tighter groups downrange. The integrated cutout in the die body gives you a clear sightline to verify case alignment and confirm depth setting without guesswork. That detail matters when you're loading ammunition intended for hunting or competition where a round's uniformity can make the difference.

Built from stainless steel, this die is engineered to outlast countless reloading sessions. It ships with one .256'' mandrel; L.E. Wilson offers additional caliber-specific mandrels separately, so you can adapt this die to other calibers as your reloading grows. The included L.E. Wilson lock nut (measuring .225" thick, .270" tall, and 1.250" OD) secures the die with the precision fit the brand is known for. Made in the USA, it reflects L.E. Wilson's long reputation for accuracy-focused reloading equipment.
