Lee Factory Crimp Die .404 Jeffrey

In the realm of precision shooting, where accuracy reigns supreme, even the smallest details can make a significant difference. Enter the Lee 404 Jeffery Factory Crimp Die—a tool designed to enhance your ammunition's performance with uncompromising reliability. This custom over-run crimp die features an impressive 1 1/4-12 thread and is engineered to crimp bullets more firmly than any other instrument available.

What sets this crimp die apart is its ability to improve accuracy through a firm grip on the bullet. Tests have shown that even those projectiles lacking a traditional crimp groove benefit from this enhanced hold, achieving greater precision downrange. The science behind it lies in creating higher start pressure; before movement begins, pressure builds up more substantially within the cartridge chamber.

Such elevated start pressure results in a uniform pressure curve as well as reduced velocity variation—key factors for consistent shot placement and heightened ballistic performance. For shooters seeking dependable accuracy and improved outcomes with their equipment, the Lee 404 Jeffery Factory Crimp Die stands ready to deliver.
