Lee carbide undersize sizing dies are designed for reloaders seeking optimal feeding reliability. These dies size brass cases between 0.002 inches and 0.003 inches smaller than standard Lee sizing dies, ensuring consistent chambering as the case is stripped from the magazine. Additionally, the die enhances and stabilizes neck tension on loaded bullets, thereby improving accuracy. The carbide construction prevents belt marks on the cases. While lubrication is not necessary when using carbide dies, applying a small amount of case lube can facilitate the sizing process. Please note that the shell holder is not included.

Lee's undersized carbide sizing dies feature a precision-engineered diameter that is 0.003 inches smaller than our standard carbide sizing dies, optimizing fit and performance for specialized applications
