The Lee Factory Pistol Crimp Die for .357 Sig uses a carbide sizer to post-size pistol cartridges while applying a factory-style crimp. The design crimps the bullet in place more firmly than ordinary tools, which can lead to more uniform pressure development. A firmer crimp helps reduce velocity variation for more consistent reloads.
