Lee 30-30 Winchester Factory Crimp die
Produsent: LEE

Lee 30/30 Winchester or 30/30 Ackley Improved 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.
