The Lee 204 Ruger Factory Crimp Die ensures a firmer crimp on your bullets than any other tool, enhancing overall accuracy and performance. Even bullets without a crimp groove benefit from this die, as tests show that a firm crimp improves shot consistency. The die works by requiring pressure to build to a higher level before the bullet begins to move, resulting in a more uniform pressure curve. This higher start pressure reduces velocity variation, contributing to greater accuracy and a more reliable shot every time. Whether you're reloading for precision or performance, the Lee Factory Crimp Die helps ensure the highest level of consistency.
