Lee Precision .356 Winchester-358 Winchester Factory Rifle Crimp Die

Overview

The Lee Precision Factory Crimp Die for .356 Winchester and .358 Winchester is a reloading tool that uses a collet to apply a firm, uniform rifle-style crimp to the case mouth. By squeezing the case against the bullet, this die secures the projectile more firmly than traditional roll crimp dies, which helps prevent bullet setback and improves accuracy. This uniform crimp increases the start pressure required for ignition, leading to a more consistent pressure curve and reduced velocity variation. It is effective even for bullets that lack a dedicated crimp groove.
