Lee 300 Weatherby Factory Crimp Die
Incorporates a collet to apply a rifle-type crimp to the case. It makes even the most 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. A firm crimp improves accuracy because pressure must build to a higher level before the bullet begins to move. This higher start pressure ensures a more uniform pressure curve and less velocity variation.
