Product Information

Many reloaders consider Lyman’s Neck Expanding (M) Die a valuable tool for improving the accuracy of their reloads. The die’s expander plug has two steps. The first step expands the inside of the case neck to just under bullet diameter for precise case neck tension in the finished reload. The second step expands the case mouth to bullet diameter or slightly over. This allows the jacketed or cast bullet to be started perfectly centered in the case mouth and properly aligned with the axis of the case neck. (By adjusting the neck expanding plug slightly deeper, Step 2 also provides a slight flaring of the case mouth for reloaders using cast bullets.)

First time of using such a product worked as stated!

Easy to use

By Michael E. on Aug 22, 2019
I have one for each of my rifle calibers. When I outside turn the necks I just adjust this up for expanding the neck only and when I want to be able to start the bullets in the neck before seating I just adjust it down. I use this to expand the inside of the neck for outside turning on my Hornady neck turning tool. I pull the expander ball from my Forster dies when full length resizing the case then use this die for expanding the inside neck perfectly to fit the Hornady undersized arbor. Only need to do this once so after this I use the expander button in the die to full length resize. Works great
