The Hornady Full-Length Size Die for the 7x57R Rimmed Mauser is a precision reloading tool designed to resize fired brass back to SAAMI minimum dimensions, readying cases for the next loading cycle. Part of Hornady's Custom Grade range, it is machined to exacting tolerances and features a polished internal profile that prevents case sticking and minimises friction throughout the stroke. The Elliptical Expander — a Hornady exclusive — offers a clear advantage over conventional ball expanders: it expands the case neck smoothly, significantly reducing friction and limiting neck stretch to extend case life. Internal threading locks the expander assembly securely in place, while the Zip Spindle allows quick coarse adjustment by zipping up or down the spindle, with fine-threaded locking to eliminate any slippage once set. The included Sure-Loc lock ring clamps around the full die body, applying uniform pressure without bearing on the threads, and the incorporated wrench flats make swapping dies simple. Fits any standard 7/8-14 inch reloading press. Backed by Hornady's no-risk lifetime guarantee. Made in the USA.
