The LEE case expander die is an essential tool designed to precisely and uniformly expand the mouth of metallic cartridge cases. This expansion facilitates the smooth seating of projectiles, particularly lead bullets that retain their original grease or lubricant coatings, which must not be removed to maintain optimal ballistic performance and barrel fouling prevention.
Specifically engineered for precision handloaders and ballistic enthusiasts, this die allows for controlled expansion of the case neck, ensuring consistent bullet seating tension and improved accuracy. The slight flare created by the expander die reduces the risk of bullet deformation during seating, which is critical when working with soft lead or semi-metallic projectiles.
Additionally, the die features a top-loading powder funnel, enabling manual powder charging directly into the case neck. This design supports both measured powder drops and bulk powder pouring, facilitated by the integrated funnel, streamlining the reloading process while maintaining safety and precision.
By removing the upper threaded cap, users can attach a disc powder measure, which simultaneously expands the case mouth and meters the exact powder charge into the case. This dual functionality optimizes workflow efficiency and ensures consistent powder charges, critical for maintaining uniform muzzle velocities and ballistic consistency.
It is imperative to ensure that the cartridge case is fully seated on the shell holder before powder charging to prevent powder spillage onto the press, which could lead to contamination or hazardous conditions. Proper case positioning also guarantees accurate powder measurement and reliable ignition.
Designed for compatibility with a wide range of calibers and reloaders, the LEE case expander die is a vital component in the metallic and semi-metallic reloading process, enhancing both the safety and precision of ammunition assembly for hunters, competitive shooters, and ballistic technicians.
