With the Collet neck Die a collet squeezes the case neck against a precision mandrel for a perfect fit with minimum run-out. No lube case is needed. Cases last ten times longer, so the savings on only 100 cases will pay for the dies. You also have the option of full length resizing with the Lee Deluxe Die Set which also includes a seating die and a shell holder. Surely the best value die set on the market.
