Dillon Precision 45 Long Colt seating die

Dillon Precision .45 Long Colt seating die

The seating die is the die that pushes the bullet into the case mouth of the primed casing, seating it to the set depth and thus to the desired overall cartridge length. This version handles the .45 Colt caliber.

Adjustment is performed via the seating stem, which is screwed in or out to vary the seating depth: in the Dillon range, the stem is a separate component, allowing it to be chosen based on the bullet profile in use. On Dillon presses, crimping is handled by a separate die, which allows for independent adjustment of seating depth and case mouth closure. Dillon manufactures its own pistol carbide dies in the United States, hand-crafting them from sintered carbide and hand-finishing them to tight dimensional specifications. The manufacturer specifies that these dies are not compatible with the Square Deal B press, which uses proprietary components.
