Hornady Series 1 Full Length Die Set for 7mm Remington Ultra Magnum

The Hornady Series 1 Full Length Die Set for 7mm Remington Ultra Magnum gives you a matched pair of precision dies built to handle one of magnum rifle's most capable cartridges. If you're loading for a 7mm RUM—whether you're chasing elk across open country or pushing accuracy at distance—a quality full-length die set is the foundation of consistent, safe ammunition. Hornady's Custom Grade dies are machined to exacting standards with internal finishes that reward careful reloaders with repeatable results year after year.

This two-die set includes everything you need to resize fired brass and seat bullets. The design centers on the Zip Spindle system, which locks positively to the die body and eliminates slippage during setup and adjustment. Fine threads on both the spindle and spindle collet let you dial in precise incremental changes—handy when you're working up a load or fine-tuning bullet seating depth—while the ability to zip up or down quickly keeps your workflow moving.

Hornady backs these dies with a no-nonsense guarantee: they won't break or wear out under normal use. That confidence comes from decades of die-making experience and attention to detail in every component. The set includes smooth-finish lock rings with wrench flats, making it easy to secure your dies in a press without marring them. An in-line bullet seating system, built-in crimper, and retainer ring round out the package, and everything arrives in its own dedicated die box for safe storage and transport.
