Lee Precision 92187 Factory Crimp Die 22 Arc

The Lee Precision 92187 Factory Crimp Die for 22 Arc is a specialized reloading die designed to deliver consistent, precise crimping for shooters who demand tighter ammunition control. Unlike standard sizing dies, this factory crimp die applies uniform pressure to the case mouth around the bullet's crimp groove—or works effectively even on bullets without a dedicated groove. That firm, controlled crimp is what separates match-grade handloads from acceptable ones: it prevents bullet creep during firing, stabilizes pressure buildup, and flattens velocity variation across your string of shots.

If you're loading 22 Arc for precision rifle work, hunting, or competitive shooting, you know that marginal ammo tolerance kills groups. A factory crimp die tightens that tolerance. By squeezing the case mouth with a collet that holds the cartridge securely, this die ensures every round experiences the same crimp pressure—which means more predictable pressure curves and tighter velocity spreads. That translates to smaller groups downrange, especially at distance where even minor velocity variations show up in bullet drop.

The die is compatible with all standard 7/8"-14 thread reloading presses, so it'll drop into your existing setup without modification. Note that a shellholder is not included, so verify you have the correct holder for 22 Arc before you load. This is the final step in your reloading sequence—after sizing, priming, powder charging, and bullet seating—and it's the difference between "loaded" and "match-grade."

Frequently Asked Questions

Will this crimp die work with my reloading press?

Yes, if your press has a 7/8"-14 die thread. This is the standard size for most single-stage and turret presses. Check your press manual or measure the die hole if you're unsure.

Do I need a shellholder, and what size does 22 Arc use?

Yes, a shellholder is required and is not included with this die. Verify the correct shellholder for 22 Arc before ordering separately; using the wrong size will result in improper crimping.

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

A seating die pushes the bullet into the case; a factory crimp die then crimps the case mouth around the bullet after seating. A factory crimp die applies firmer, more consistent pressure than the crimp collar on a seating die alone, which improves accuracy and pressure consistency.

Will this crimp die work on bullets without a crimp groove?

Yes. The Lee factory crimp die's collet mechanism squeezes the case mouth uniformly, so it crimps effectively even on plain-jane bullets without a dedicated groove—improving accuracy over no crimp at all.
