The Lee Deluxe Carbide 4-Die Set combines the world's most popular carbide three-die set with the Lee Carbide Factory Crimp die at a great price. By separating the seating and crimping operation, you will benefit by greatly simplified adjustment. Since the Lee Expander Die flares the minimum amount, consistent with easy bullet insertion, all of the flare is removed with the bullet seating die thus eliminating the need for a taper crimp die. The Carbide Factory Crimp Die post sizes the case assuring that any round that passes through the die will chamber properly in your gun. Full length carbide sizing die, expanding die, bullet seating die, carbide crimp die, shellholder, powder measure, load data and storage box included.
