Description

To be used with the NEW Wilson Expanding Mandrel Sizing Die. Designed to be used on NEW brass cases to prepare the case for the seating opeation. 

Over the past few years we have seen a greater need to run new brass cases over and expanding mandrel to properly prepare them for their first firing.  New brass cases are often damaged when shipped in bulk, this die will give you a consistant neck diameter on your cases.  With correct neck tension you can expect a more consistant seating depth and shot!

    Very well made and should last a very long time.

    I was looking for expander mandrels for setting neck tension, and these are 1. perfect and 2. in stock. Machining is perfect as you’d expect from Wilson and KAS actually had them in stock and got them to me in a timely manner.
