Key Specifications

• 380 ACP/9mm Luger is the cartridge this die is machined to size, expand, seat, or crimp.
• Case Expander Die function: this die flares the case mouth just enough to start a bullet straight without shaving the jacket or lead, the step that comes right after resizing and before seating.
• Precision-machined internals: the die is drilled to accept an optional powder-through insert, so it can double as the charging station on a progressive press.
• 7/8-14 threaded die body drops into any standard single-stage, turret, or progressive press without an adapter.
• Precision-machined steel construction holds tight tolerances through years of repeated reloading sessions.

Frequently Asked Questions

What does this case expander die do? Flares the case mouth just enough to start a bullet straight without shaving the jacket or lead, the step that comes right after resizing and before seating.

Why expand the case mouth before seating a bullet? It keeps the bullet from shaving lead or jacket material as it enters the case, which keeps bullet pull and seating depth consistent round to round.
