The LEE case expander die is an essential tool designed for precision metallic and semi-metallic reloading processes, specifically engineered to slightly expand the neck of cartridge cases. This expansion facilitates the smooth and consistent seating of projectiles, particularly lead bullets that retain their factory-applied lubricant or grease, which must not be removed to maintain optimal ballistic performance and barrel fouling reduction.
Utilizing this die ensures uniform neck expansion, which is critical for maintaining proper bullet tension and concentricity during the reloading cycle. The controlled expansion prevents damage to the bullet jacket and preserves the integrity of the lubricant coating, essential for minimizing barrel leading and enhancing accuracy in precision shooting disciplines.
Additionally, the die features an integrated powder funnel at its upper section, allowing manual powder charging directly into the case neck. This design supports precise powder measurement and transfer, either by filling the funnel with a predetermined charge or by using a powder scale in conjunction with the funnel to ensure consistent powder loads, vital for safe and reliable ammunition performance.
For advanced reloading setups, the top threaded cap of the die can be removed to install a disc-type powder measure. This innovative accessory simultaneously expands the case neck and deposits an exact, pre-selected powder charge into the case, streamlining the reloading process and enhancing throughput without compromising safety or precision.
It is imperative to ensure that the case is firmly seated and properly supported on the shell holder before expansion to prevent powder spillage onto the press mechanism, which could lead to operational hazards or contamination. Proper case positioning also guarantees consistent neck expansion and powder charging, contributing to overall ammunition quality and reliability.
Optimized for reloaders specializing in metallic and semi-metallic cartridge preparation, the LEE case expander die is a vital component for achieving consistent bullet seating, precise powder charges, and superior ballistic results in both competitive and hunting applications.
