Lee Carbide Factory Crimp Die .38 Special/.357 Magnum

Lee Carbide Factory Crimp Die for .38 Special and .357 Magnum

This specialized reloading die from Lee Precision represents a critical step in producing reliable, accurate handgun ammunition. The factory crimp die performs two essential functions simultaneously: it sizes the cartridge while applying a precise crimp, ensuring every round chambers freely with factory-like dependability.

Key Features

• Carbide Construction: Durable carbide sizing ring eliminates the need for case lube
• Simultaneous Sizing and Crimping: Cartridge is sized while being crimped in a single operation
• Roll Crimp Application: Applies a firm, consistent roll crimp that's essential for reliable ignition
• Adjustable Crimp: Quick-set adjusting screw allows you to dial in the exact amount of crimp needed
• Time-Efficient: Trim length is not critical, saving time compared to separate trimming and chamfering operations

Why Crimp Matters

A firm, properly applied crimp is fundamental to ammunition reliability and accuracy. It eliminates ignition problems—particularly critical when using slow-burning magnum powders. Without proper crimping, you risk inconsistent powder burn rates and velocity variations that degrade accuracy and reliability.
