Lee 7MM Rem Mag / 7 x 64 Brenneke Factory Crimp Die crimps the bullet more firmly than any other tool. Tests demonstrate that even bullets that have no crimp groove will shoot more accurately. A firm crimp improves accuracy because pressure must build higher before the bullet begins to move. This higher start pressure ensures a more uniform pressure curve and less velocity variation.
