The Hornady Full-Length Size Die for 7x57 / 7mm Mauser (.284) sizes fired cartridge cases back to SAAMI minimum specifications, making it an essential tool for the handloader who wants consistent, accurate reloads from this classic stalking and target calibre. Precision machining throughout ensures smooth, reliable operation, while the proprietary Elliptical Expander delivers superior neck sizing compared to conventional ball expanders — reducing friction and case neck stretch in a single pass. The Elliptical Expander and headed decap pin are mounted to Hornady's Zip Spindle, which locks positively to prevent slippage and allows both fine incremental adjustment via light thread engagement and rapid coarse movement when needed. Internal threading retains the expander securely, and the polished internal die profile prevents case sticking or excessive friction. The included Sure-Loc lock ring clamps around the full die body for consistent pressure without thread contact, with wrench flats machined in for easy fitting and removal. Backed by Hornady's lifetime guarantee against breakage or wear under normal use, this die is made in the USA to exacting tolerances.
