Lyman Neck Expanding "M" Die - 38 Spec/357 Mag/357 Rem Max/38 S&W

The Lyman “M” die Improves accuracy of cast and jacketed bullet reloads. It doesn't stretch the case mouth as does a standard expander button which in turn should extend case life. 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. For the following cartridges: 22 Hornet
