14404 Pistol Dies (three-die sets) - .45 ACP Sizing/Depriming Die - Our sizing/depriming dies feature a unique "floating decap assembly" with a snap spring that throws the spent primer off the pin and eliminates the problem of primer "draw back" that often occurs when decapping military brass. Bullet Seating Die - Our new quick-disassembly seat die allows the user to disassemble and clean the seat die without losing adjustment. Crimp Die - We've made it easy for you to remove the die insert for cleaning without having to change the critical crimp adjustment. NOTE: All Dillon Pistol Die sets include our sizer/ decap die, seat die and a separate crimp die. (Taper crimp for autos; accu-crimp for revolvers.)
