Lee 7x57 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 7x57 Rimmed Mauser uses the standard 7x57 dies, but will need a different shell holder to hold the case. The Rimmed cases would use a #5 Shell Holder.
