Lee 7x57mm Mauser (R) Factory Crimp die
Produsent: LEE

Lee 7×57 Mauser 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.

**Note: The 7×57 Rimmed Mauser uses the standard 7×57 dies, but will need a different shell holder to hold the case. The Rimmed cases would use a #5 Shell Holder.
