Precision, smoothness and versatility are hallmarks of Lyman Precision Dies. Each rifle sizing die is vented, polished, heat treated for toughness and final microfinish-polish for extra smoothness. Solid, one-piece decapping rods are made of hardened, heat-treated tool steel. Ideal for loading jacketed bullets in bottleneck rifle cases. Includes a full-length resizing die with decapping stem and neck-expanding button, plus a bullet-seating die.
