Lee 280 Remington (7mm Express) Factory Crimp die
Produsent: LEE

Lee 7mm Express, 280 Remington, 280 Original Ackley Improved, 280 SAAMI 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.
