Lee Factory Crimp Die .404 Jeffrey, Lee 404 Jeffery [1 1/4-12 thread] Factory Crimp Die (custom over-run) 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.
