LEE FACT CRIMP DIE 5.7X28 FN

LEE FACT CRIMP DIE 5.7X28 FN. 7x28 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.
