LEE Factory Crimp Die 5.7x28 FN

DESCRIPTION

Lee 5.7x28 FN Factory Crimp Die crimps the bullet firmly in place. 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.

Incorporates a collet to apply a rifle type crimp to the case. Makes these very difficult to crimp cartridges a delight to reload. Bullets do not need a crimp groove, as the collet is so powerful it will form one. Lee 5.7 x 28 FN Bottle Neck Factory Crimp Dies crimps the bullet firmly in place for the bottleneck cartridge.
