Lyman Pro Series Micrometer Taper Crimp Die - 380 Acp

If you're serious about consistent, match-grade handgun ammunition, the Lyman Pro Series Micrometer Taper Crimp Die for .380 ACP puts precision control in your hands. Unlike standard crimp dies where you're guessing at the seating depth, this die's micrometer-adjustable head lets you dial in the exact crimp you want, down to a few thousandths of an inch. That level of control is what separates reloads that feed and chamber smoothly from ammunition that causes feeding issues or case damage.

The floating crimp sleeve design centers each cartridge before applying the taper crimp, ensuring consistent results across every round you load. Whether you're running a tight match chamber or just want ammo that feeds reliably through your carry gun, you get the repeatability that only a precision tool can deliver. And because it's built from corrosion-resistant stainless steel, it'll hold up to years of bench use without rust or wear.

This is purpose-built for reloaders who understand that .380 ACP—compact, low-power, and fussy about feeding—demands better ammunition than factory rounds. A micrometer crimp die transforms your reloading from a simple process into a controlled precision task.

Key Features

Frequently Asked Questions

What's the difference between a micrometer crimp die and a standard crimp die?

A standard crimp die has a fixed crimp amount you can't adjust; a micrometer crimp die lets you turn the adjustable head to change the crimp depth in thousandths of an inch. This means you can fine-tune the crimp to your specific chamber and ammunition setup instead of taking whatever the die gives you.

Is this die compatible with my single-stage or progressive press?

We don't have press compatibility details for this die in our current specs. Check with Lyman's website or contact their support team to confirm it fits your specific reloading setup.

Will this die work with any .380 ACP brass and bullets?

This die is designed for .380 ACP ammunition. Since it's a taper crimp die (not a roll crimp), it's suited for rimless cartridges like the .380—but for specific bullet and brass compatibility questions, consult Lyman's reloading manuals or customer support.

What maintenance does the stainless steel die need?

Stainless steel resists corrosion, so routine care is minimal—wipe it down and store it in a dry place. Don't let it sit wet or in a humid environment, and avoid solvents that might affect the micrometer mechanism.
