Dillon Precision 45 ACP caliber crimping die

Dillon Precision .45 ACP caliber crimp die

The crimp die is the final die in the cycle: it closes the case mouth over the already seated bullet, securing it and restoring the profile necessary for the cartridge to chamber correctly. This version is for the .45 ACP caliber.

For semi-automatic pistol cartridges, Dillon uses a taper crimp, which closes the case mouth onto the bullet without cutting it; this is the correct closure for cartridges that headspace on the case mouth. On Dillon progressive presses, the crimping is performed by a die separate from the bullet seating die, allowing for independent adjustment of bullet seating depth and case mouth closure. Dillon manufactures its carbide pistol 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.
