Lee 90931 Collet Crimp Die for .500 S&W Magnum

The Lee 90931 Collet Crimp Die is designed for reloading .500 S&W Magnum cartridges with a powerful, rifle-style collet crimp. This specialized die provides a reliable way to secure bullets in one of the more demanding handgun cartridges, helping improve bullet retention and support consistent ammunition performance. Its collet-style design applies even pressure around the case mouth rather than relying on a conventional crimp groove in the bullet.

The collet is strong enough to form a crimp groove in bullets that do not already have one, giving reloaders greater flexibility when selecting projectiles. This makes the die especially useful for bullets with smooth shanks or designs that lack a dedicated crimp groove. The controlled crimp helps hold bullets firmly in place during handling, feeding, and recoil while supporting a consistent finished cartridge.

This Lee die is intended specifically for .500 S&W Magnum ammunition and is supplied as a single crimp die. It is a collet-style crimp die, not a sizing or seating die, and should be used as part of a compatible reloading setup. The die is not carbide, so proper case preparation and lubrication practices should be followed when required by the reloading process. As with all reloading equipment, follow published load data and established safety procedures when setting up and using the die.
