Lee Precision .450 Bushmaster Factory Crimp Die - 91167

Introducing the factory crimp die, featuring a collet design that imparts a rifle-style crimp onto the case. This innovation transforms even the most challenging-to-crimp cartridges into a reloading pleasure. Remarkably powerful, the collet's action eliminates the necessity for bullets to possess a crimp groove, it has the capacity to shape one. The firm crimp not only enhances accuracy by requiring higher pressure before bullet movement but also ensures a more consistent pressure curve and reduced velocity fluctuation. Please note that this die is not carbide-coated.
