The Challenger III features the classic "O" frame design-renowned for its strength and stability-making it one of the most popular press styles on the market. Its extra-large 4" opening provides excellent hand clearance, making operation smoother and more comfortable. The press includes the Lee Lever Prime System, offering effortless and reliable priming. It also comes equipped with the Breech Lock Quick Change Die System, allowing you to swap dies instantly with a simple twist-no need to re-adjust settings. An ergonomic lever improves comfort and efficiency, with an optimized priming position that eliminates the need to stoop during operation. The through-ram primer disposal system channels spent primers directly through the ram into an easy-to-empty collection tube, keeping dirt and debris away from the press frame and ram. Also included is the Breech Lock 3-Die Set, featuring color-coded Smart Lock bushings for quick die identification. The set includes a Carbide Full Length Sizing Die, Bullet Seating Die, Powder-Through Expanding Die, a Universal Shell Holder, Powder Dipper, and complete Instructions with Load Data.
