LEE Factory Crimp Die 300 Ultra Mag

DESCRIPTION

Lee 300 ULTRA MAG and 300 H&H Factory Crimp Die crimps the bullet in place more firmly than any other tool. 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.
