Description
The Lee 375 H&H Factory Crimp Die crimps the bullet in place more firmly than any other tool, which improves accuracy. Tests demonstrate that even bullets that have no crimp groove will shoot more accurately. A firm crimp also ensures a more uniform pressure curve and less velocity variation.
Lee 375 H&H Factory Crimp Die crimps the bullet in place 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 to a higher level before the bullet begins to move. This higher start pressure insures a more uniform pressure curve and less velocity variation.
