Lee Precision 25/20 Factory Crimp Die

25/20 Factory Crimp Die Features Lee 25/20 Factory Crimp Die crimps the bullet in place more firmly than any other tool. Tests demonstrate that even bullets that 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. 25/20 Factory Crimp Die Specifications Holds bullet in place improves accurac
