The Lee Factory Crimp Die - 300 WM 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.
