Lee 22 Creedmoor Custom Factory Crimp Die

The Lee 22 Creedmoor Custom Factory Crimp Die (Model 92179) is a specialized reloading tool designed to apply a rifle-type crimp directly to cartridge cases using an integrated collet mechanism. Unlike standard sizing dies, this crimp die delivers a firm, consistent crimp that improves accuracy by ensuring uniform pressure curves and reducing velocity variation—critical factors for long-range precision shooting with the 22 Creedmoor cartridge.

The collet design is exceptionally powerful, capable of forming a crimp groove directly into the case even when bullets lack a dedicated crimp groove. This eliminates the need for specialty ammunition and simplifies the reloading process for difficult-to-crimp cartridges. A firm crimp forces bullet pressure to rise to a higher threshold before movement occurs, establishing a more controlled and predictable pressure curve that translates directly to tighter velocity spreads and improved group consistency on the range. Weighing just 0.3 lbs with compact dimensions (1.5 x 1.5 x 4.75 inches), the die integrates seamlessly into standard press setups.

This die suits reloaders who demand maximum consistency from precision rifle cartridges, particularly those shooting 22 Creedmoor for long-range competition, hunting applications, or controlled-load development. Handloaders who have struggled with marginal bullet retention or inconsistent ignition will find the Lee crimp die's collet action addresses these issues directly. The 22 Creedmoor has gained strong adoption in precision rifle circles, and proper case preparation—including controlled crimping—distinguishes quality reloading from basic ammunition assembly.

Lee Precision manufactures this die in steel construction (note: not carbide). It is a single-station tool intended for use with a manual or powered single-stage or turret press. Proper setup and operation require familiarity with standard reloading procedures and Lee press equipment compatibility.
