Hornady Custom Grade New Dimension Series II Handgun 3-Die Set 380 Auto .355"

The Hornady Custom Grade New Dimension Series II Handgun 3-Die Set for .380 Auto .355" delivers precision reloading components engineered for shooters who demand consistency in ammunition production. This three-die set combines proven New Dimension engineering with refinements designed specifically for handgun cartridge reloading, addressing the unique dimensional and neck-sizing requirements of the .380 Auto caliber.

The set features Hornady's Zip Spindle design with light threads cut on both spindle and spindle collet, eliminating spindle slippage during adjustment and tightening operations. Wrench flats on Sure-Loc long rings provide firm grip for precise die positioning, while the headed steel decap pin delivers reliable primer pocket cleaning. An elliptical expander polished to a smooth finish minimizes friction and bullet seating resistance, and the all-steel seater adjustment screw with compression washer ensures locked-in depth settings across reloading sessions. The .355" specification matches standard .380 Auto bullet diameter, critical for proper neck sizing and bullet engagement during the reloading cycle.

This die set suits handgun reloaders working with .380 Auto ammunition for defensive carry loads, range training, or precision testing. The three-die configuration covers full-length sizing, decapping, and bullet seating—the core operations for consistent handgun ammunition. Reloaders prioritizing shot-to-shot consistency, minimal tool slippage during setup, and repeatable seating depths will find the Series II platform addresses common frustrations in smaller-caliber handgun reloading workflows.

Custom Grade die sets from Hornady represent the manufacturer's premium reloading line, differentiated from standard offerings through tighter tolerances, enhanced materials in critical wear points, and refined ergonomics in spindle and adjustment mechanisms. For reloaders operating progressive or single-stage presses, the New Dimension Series II platform has become a reference standard in handgun ammunition assembly.
