Lyman | M Neck Expander Die
The Lyman Neck Expander Die improves accuracy of cast and jacketed reloads. Extends case life. A must have die for the cast bullet or flat-base bullet user. The first step in the expander stem 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 larger. This allows the cast or jacketed bullet to be started perfectly centered in the case mouth and properly aligned with the axis of the case neck. By adjusting the plug slightly deeper, the second step also provides a slight flaring of the case mouth for reloaders using cast bullets.
