The Lee 90930 .44 Remington Magnum Crimp Die Set is a specialized reloading die designed to handle one of the most demanding handgun cartridges in the reloader's vault. The .44 Remington Magnum is notoriously difficult to crimp properly using standard die designs, but Lee's Factory Crimp Die approach solves that problem with a collet-based system that applies a rifle-style crimp to magnum-class pistol cases. If you've struggled with loose bullets and inconsistent crimps on .44 Mag loads, this die transforms a frustrating step into a reliable, repeatable process.
What makes this die unique is its collet mechanism, which exerts enough force to form a crimp groove directly into the case shoulder—even on bullets that don't feature a traditional crimp groove. That means you're not limited to specialty ammunition or pre-grooved bullets; standard projectiles work just fine. The result is a crimp that's secure enough for magnum powders and velocities, improving shot-to-shot consistency and reducing the risk of bullet setback during feeding or recoil.
This is a purpose-built tool for serious .44 Magnum handloaders—hunters, competition shooters, and precision revolver enthusiasts who demand dependable ammunition. The Lee collet-style crimp die is a workhorse addition to any magnum handgun reloading setup, especially if you've been troubleshooting crimp issues or upgrading from a standard seating/crimp combo die.
The Lee 90930 is designed for use with standard reloading presses that accept .44 Magnum dies. Verify that your press can accommodate standard die threads and spacing before purchase.
No. The collet mechanism in this die is powerful enough to form a crimp groove in the case shoulder itself, so standard bullets without pre-cut crimp grooves will work just fine.
A Factory Crimp Die applies a crimp by collapsing the case mouth onto the bullet, similar to how factory ammunition is crimped. The .44 Remington Magnum is notoriously difficult to crimp with conventional seating/crimp combo dies, making a dedicated factory crimp die the solution for consistent, secure loads.
This is listed as a die set; verify the exact contents (die, shell holder, instructions, etc.) with your order details, as set configurations can vary.
