Buy on Ammo Depot

The Lee .356-358 Winchester Factory Crimp Die is a reloading die built for .356 Winchester and .358 Winchester cartridges. It applies a factory-style crimp that grips the bullet firmly, even on bullets that have no crimp groove, so cases stay properly secured through handling and feeding. The tighter crimp raises start pressure, which promotes a more uniform pressure curve and less shot-to-shot velocity variation.

Reloaders use it as a dedicated crimping step alongside their existing sizing and seating dies, and it is suited to both hunting and target ammunition in .356 Win / .358 Win. The die carries model number 90904.
