Lyman Pro Series Micromemter Taper Crimp Die - 308

The Lyman Pro Series Micrometer Taper Crimp Die for .308 is built for reloaders who demand precision on every round. This stainless steel die gives you fine-tuned control over crimp depth—dial in exactly what your loads need, from subtle tension to firm seating, in thousandths-of-an-inch increments. The floating crimp sleeve centers your cartridge and applies a consistent taper crimp across your entire batch, which matters when you're working up loads for accuracy or feeding through a semi-auto that's finicky about case neck tension.

If you've ever found yourself adjusting a standard crimp die by feel or shimming it to dial in the perfect setting, you'll appreciate what a micrometer head brings to the bench: repeatability without guesswork. Once you've dialed in your crimp for a given bullet and brass combination, you lock it in and move on. No more hunting. Lyman built this die in corrosion-resistant stainless steel, so it'll hold up to the damp corners of the reloading room and the occasional spill without pitting or rust.

This is a .308-specific die, so make sure it matches your cartridge before ordering. Whether you're fine-tuning match ammo, developing hunting loads, or just tired of resizing-die adjustment hassles, a micrometer crimp die pays for itself in saved time and consistency.

Specifications

Frequently Asked Questions

Is this die compatible with my .308 Winchester or 7.62×51 NATO brass?

This die is caliber-specific to .308. It will work with .308 Winchester cartridges and brass. If you're using 7.62×51 NATO brass, verify compatibility with Lyman before ordering, as NATO dimensions can differ slightly.

What's the advantage of a micrometer crimp die over a standard crimp die?

The micrometer head lets you make precise adjustments in tiny increments and repeat the exact same crimp setting every time without guessing or trial-and-error. Once you dial it in, your crimp depth stays consistent across hundreds of rounds.

What does this die do, and will I need other dies for a complete reload?

This is a crimp die only—it applies the final crimp to your case and bullet. You'll also need a separate sizing die, decapping die, and seating die to complete a full reloading sequence for .308.

Is this die made to last, or will it rust in my reloading room?

Lyman manufactured this die in stainless steel specifically to resist corrosion and rust, so it will hold up to humid or damp shop conditions and maintain its finish for years of use.
