In addition to enhancing feeding reliability, the die also stabilizes neck tension on loaded bullets, which is crucial for improving accuracy. The carbide construction of the die is particularly beneficial as it prevents belt marks on the cases, maintaining their integrity and appearance. While the use of lubrication is not mandatory with carbide dies, applying a small amount of case lube can make the sizing process smoother and more efficient.
