LEE Factory Crimp Die 7.62x54mm Rimmed Russian + 7.62x53mm Rimmed #90842

Lee 7.62X54 Russian and 7.5 x 54 MAS 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.
