Lee Carbide Breech Lock Bushings 4-Die Set .380 Auto

The Lee Carbide Breech Lock Bushings 4-Die Set .380 Auto is a complete reloading solution designed for precision handloaders who demand consistency and reliability in ammunition production. This four-die set includes carbide dies for both full-length sizing and factory-crimp finishing, simplifying die identification and setup.

Lee Precision engineered this kit to deliver repeatable chamber fit and bullet seating depth across production runs. The set comprises a carbide full-length sizing die, powder-through expanding die, bullet seating die, and carbide factory crimp die—the latter a critical component for .380 Auto reloads, which benefit from consistent case mouth control to ensure reliable feeding and extraction.

Serious handloaders will appreciate the efficiency and precision this set brings to their reloading process. The included accessories, such as a Universal Shell Holder and Load Data Instructions, enhance the usability of the set, making it an excellent choice for those looking to reduce ammunition costs while maintaining tight tolerances.
