Hornady Custom Grade New Dimension Series Ii Rifle 3-Die Set .405 Jeffery

The Hornady Custom Grade New Dimension Series II rifle 3-die set for .405 Jeffery is built for handloaders who demand precision and reliability across the full reloading cycle. This three-die set brings Hornady's reputation for quality control to an often-overlooked caliber, giving you the dedicated tooling needed to produce consistent, accurate ammunition for your .405 Jeffery rifle. Whether you're loading for a vintage dangerous-game rifle or a modern build, this set handles the full-length resizing, bullet seating, and crimping operations in a single, coherent system.

The Custom Grade New Dimension Series II platform uses Hornady's Zip-Spindle design, which employs precision threads on both the spindle and collet to eliminate slippage during die adjustment. This mechanical lock ensures that once you dial in your die position, it stays put—critical when you're working up accurate loads or maintaining run-to-run consistency across multiple reloading sessions. The dies are precision-machined to tight tolerances, so you can count on reliable performance across hundreds of reloads.

Because .405 Jeffery is a less common cartridge, finding quality, purpose-built tooling is genuinely challenging. This set removes that friction and lets you focus on what matters: developing loads that shoot. Hornady's three-die approach covers everything you need for standard rifle reloading without forcing you to hunt down individual dies or compromise with generic tooling designed for more popular calibers.

Frequently Asked Questions

What does this three-die set include?

The set contains a full-length resizing die, a bullet seating die, and a crimp die—the standard operations for handloading rifle cartridges. All three dies are matched and calibrated for .405 Jeffery.

Will this work with my reloading press?

This is a standard three-die rifle set. Compatibility depends on your press's die-mounting system (standard thread or specific proprietary design). Check your press documentation or contact us if you're unsure whether your equipment will accept standard Hornady dies.

Why does the Zip-Spindle design matter?

The Zip-Spindle's precision threads lock the die in place once adjusted, preventing the spindle from slipping during operation. This keeps your die position consistent from one reloading session to the next, which is essential for load development and ammunition consistency.

Is this set suitable for beginners, or is it only for experienced reloaders?

This is professional-grade tooling that suits serious reloaders. If you're new to reloading, you'll want to pair any die set with proper technique, manuals, and equipment. Because .405 Jeffery is a specialized caliber, we'd recommend having some reloading experience before tackling it.
