A Neck Size Die allows the reloader to properly size the case neck for optimal bullet tension, while maintaining the fireformed dimension of the case body. Accuracy is increased when the case body closely fits into the chamber. The Neck Size Die includes a decapping rod and steel expander button. Improve the accuracy of your standard rifle, such as the 204 Ruger, with Lyman’s Rifle Neck Size Die
