Hornady custom-grade new dimension dies represent the pinnacle of reloading die technology, offering unparalleled precision and ease of use. The innovative zip spindle design incorporates a series of light threads on both the spindle and spindle collet, effectively preventing spindle slippage and simplifying spindle adjustments. This eliminates the need for excessive force when tightening the spindle lock. Additionally, the built-in crimper provides the flexibility to crimp without requiring an additional crimp die, streamlining the reloading process. Designed for durability, these dies are guaranteed never to break or wear out under normal use. The user-friendly design allows for simultaneous seating and taper crimping in a single step, removing the necessity for a separate taper crimp die.
