Lee Precision Die 30M1 Factory Crimp
Lee 30M1 FactoryCrimping Die crimps the bullet in place more firmly than any other tool. Tests demonstrate that even bullets which have noCrimping groove will shoot more accurately. A firmCrimping 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.
