Lee Factory Rifle Crimp Die 5.7×28 FN

Description

Lee 5.7×28 FN Factory Crimp Die crimps the bullet firmly in place. Tests demonstrate that even bullets which have no crimp groove will shoot more accurately. A firm crimp improves accuracy because pressure must build to a higher level before the bullet begins to move. This higher start pressure insures a more uniform pressure curve and less velocity variation.
