Hornady Custom Grade New Dimension Series Iii Rifle 2-Die Set 7X57R Mauser
The Hornady Custom Grade New Dimension Series III Rifle 2-Die Set for 7x57R Mauser gives you the precision tooling needed to reload this classic European cartridge with confidence. This two-die set pairs a full-length sizing die with a bullet seating die, designed specifically for the 7x57R—a round that deserves better than generic, one-size-fits-all reloading solutions. Hornady's Custom Grade dies are machined to exacting tolerances and finished to a standard that stands up to thousands of reloading cycles without degradation.
Built into every Custom Grade die is the Zip Spindle system, a mechanical innovation that locks the spindle positively to eliminate any creep or slippage during adjustment. Whether you're making fine tweaks with the light threading or making bigger moves between loads, the spindle responds predictably. The seating die includes an in-line bullet seating system with a built-in crimper, keeping your setup compact and your workflow efficient. Smooth finish lock rings with wrench flats grip securely in your press without marring, and the elliptical expander seater ensures consistent neck tension shot after shot.
Hornady backs Custom Grade dies with a lifetime guarantee against breakage or wear under normal use—a confidence statement from a company that's been perfecting reloading dies for decades. The set ships in easy-access die boxes that keep your tooling organized and protected. If you're running 7x57R and want dies engineered for that specific cartridge rather than adapted from something else, this is the platform that delivers.
